An Ironman, or any triathlon for that matter, is a massive undertaking and there’s a lot that can come between you and the finish line, especially over an event that can last for up to seventeen hours.
What follows is a list of problems you could encounter and how to avoid them. Triathlon is an incredibly complicated sport, and everybody has individual needs which need to be taken into account to get you to the finish, but what are universal are the reasons for not finishing, which we will be exploring here. While this article will be angled towards Ironman as there’s simply a lot more to go wrong over a longer event, most of this advice can be applied to any distances.
Not Fit Enough
This is probably the number one reason for someone not finishing an Ironman. Excuses will be made about nutrition, pacing, blaming their equipment, but most people who fail to make the cutoffs simply aren’t fit enough. This is often the result of two possibilities, either not starting training soon enough, or doing the wrong kind of training. If you are a complete novice then hiring a coach or reading up on endurance training yourself is the best bet to get you in shape for a big event. Training for a triathlon no matter the distance is a serious undertaking and isn’t something you can simply push through like a Tough Mudder.
Arriving at the start of an event 10% undercooked is much better than arriving at an event 1% overcooked, if you are slightly undertrained you can still pull it out of the bag with some grit and determination. If you’re overtrained however you’ll struggle to get your power up to where it should be, you’ll fatigue quicker and end up very frustrated that all of the hundreds of hours you’re putting in aren’t producing results. In a worst case scenario you may even find yourself struggling to focus and find yourself weaving around a lot as your body tries to shut itself down to protect itself. The way to avoid this is to back off your training before the event (tapering), to ensure you’re raring to go on the day. It can feel counter intuitive, and you may feel like you’re losing fitness, but keeping the sessions shorter and sharper in the weeks/days leading up to the race will really help. You also need to take into account the length of your event and the priority of the event. If the race is a low priority sprint then you probably only want to back your training off in the last few days, whereas if this is a high priority Ironman event you probably want to back off for up to a month before race day to ensure your legs are good on the day. If you have a busy life with a job and a family you’ll also want more taper time than a pro who may be able to get away with a taper of a fortnight for a big event.
Accepting outside help
The vast majority of races do not permit any kind of outside help, this is either you handing people items, or them handing you items, as well as accepting mechanical assistance from spectators. You can accept help from other athletes (an inner tube if you’re lucky), but from spectators on course is a big no-no as it could give some competitors an unfair advantage by having various friends/family out on course providing nutrition.
Wrong time of the month
You know how your body reacts to different stages of your cycle so I’m not going to tell you how to manage it, but where you are in your mensural cycle can have a big effect on your race. You can use a period tracking app such as Fitr, Clue or Garmin Connect to log how you have felt at that point in previous months to ensure you know what to expect on the day. If you suffer badly with cramps it may be worth taking some pain relief with you on the bike and run.
This is a condition where the body loses salt through sweat which isn’t replaced. This can cause relatively minor symptoms such as a headache and slower stomach emptying rates, but can also cause more extreme symptoms such as blackouts, projectile vomiting, loss of co-ordination and in extreme cases slipping into a coma. The reason for this is that as the water levels increase without sufficient sodium in the system to regulate it the brain eventually starts to swell causing the above symptoms. Avoiding this is really quite simple, you need to take on salt during your event, either in the form of electrolyte tabs in your water, sports drinks, salt tablets or salty snacks. If you find yourself starting to weave about, feeling a bit disconnected or with a persistent headache then it’s worth ensuring you take some salt on at the next aid station if you don’t have any on you.
No matter how well you prepare, there’s always the possibility you’ll end up suffering with some illness on the day. Whether it’s the local cuisine backfiring or a virus you picked up on the flight, it can put you in a very difficult position. These symptoms can be exarcabated on the swim which exacerbates nausea and congestion. You’re the only one who can make the call on whether you’re able to take the start, but if you’re feeling a bit rough round the edges a PB is probably off the cards, and you might have to adjust your expectations. If your only goal is a personal best, you may want to sit this one out rather than incur the fatigue from a long day of racing, and enter another event in the near future instead. If the affliction is anything more than a stomach bug or cold though, I’d seriously recommend you sit it out to avoid any complications. There’s no way you can bulletproof yourself against illnesses, but you can make sure you back off your training in the weeks before (so your body can dedicate more energy to your immune system) and ensure sure you’re getting enough fruit and veg.
This is one of the few offences which will deny you an Ironman finish, intentionally dropping litter on the course. Traditionally this is energy bar/gel wrappers, but this also extends to bottles, visors, salt tablets or anything else you feel you have no more use for and need to relinquish as soon as possible. Harry Wiltshire discovered this at Ironman UK 2017 when he was disqualified for tossing his helmet visor which was steaming up, as even though it wasn’t litter as such (and he would have probably been back later to pick it up) it was still considered littering. If you run out of pockets/storage areas for your gel wrappers you can stuff them down your suit until you reach the next aid station. Even if you don’t get caught, the locals will take understandable umbrage to gel wrappers and C02 canisters lining their roads, making race permits harder to obtain for future years.
Giving up prematurely
During my first Ironman I had completed the first lap of the bike course and already racked up 1500M in elevation gain. I was on an energy low, my left knee was in pain and as I started my second lap, it was so very tempting to call it a day and climb off. I had the misfortune of experiencing a low point as I passed transition where it would have been easy to duck out, but I knew this was a low point that would pass, I rallied and kept going. Partly this was because I was already a seasoned triathlete by this point, partly because I knew this moment was coming. Nobody feels good for the entirety of the 180KM, and you have to trust the feeling will pass. It’s very easy/tempting to climb off, but sticking it out, taking on some more food, having a drink and using some self talk can help prevent you from calling it a day. It may feel like a good idea at the time, but you don’t want to sit at the finish watching everyone cross the line with their arms in the air, knowing you’ll have to explain to everyone why you pulled out for months on end. The best way to help with this is to really push yourself to your limit during your fitness tests so you can differentiate between when you’re genuinely done and when you just need to suck it up.
It’s very easy to make a mistake in the days leading up to the event which can prevent you even lining up at the start. While most of these are common sense to experienced competitors, they can catch out first timers.
Forgetting your photo ID
Most triathlons require a valid form of photo ID for registration, so they can ensure you’re really who you say you are. This is for the security of others as much as it is for your own protection, so don’t forget to pack your ID! In the UK a driving license or passport are the two most commonly used forms, I wouldn’t risk anything unconventional such as student or military ID.
Not registering in time
Most long distance events require you to register the day before at the very latest, at Ironman events they close registration at midday the day before, if you turn up at 12:01 you can’t race. Don’t leave it to chance, I recommend registering the day before, giving you some peace of mind in case your car breaks down or train is cancelled on the morning you’re due to head up.
Not completing your medical certificate
Not an issue in the UK, but some countries require a doctor’s letter confirming you’re in good health to compete in the event. This can normally be acquired fairly easily for a small charge, but make sure this is done in advance and you take your copy with you, otherwise you will not be allowed to take the start.
Not racking in time
Once you’ve registered you need to ensure you rack your bike and have your transition area setup in time. For shorter events this is simply so everything is ready for you when you come out the water, for longer events that normally means you have to rack the day before. If your bike isn’t racked when transition closes you can’t start the race. If you only register at the 11th hour this may only give you a few hours to get everything in place, which is unlikely to be enough for an event split transition, where T1 and T2 are separate.
So, you’ve made it to the start line, next up is the discipline which has the highest DNF (did not finish) rate in shorter events, the swim. If you are a confident swimmer there’s not a huge amount that can go wrong here, but that’s not to say you can get complacent.
You can’t swim
Let’s be honest, some people who start a triathlon just can’t swim properly. They can make an arm/leg movement that propels them forward in a fashion, but it’s exhausting and very slow. You’ll probably be able to get through your first pool triathlon like this, but in open water and/or longer distances you will be found wanting. Breaststroke is absolutely fine, you don’t even have to put your face in the water, but you do need to be able to propel yourself through the water in a relaxed, efficient manner so you can make the time cutoff without exhaustion. If the thought of the swim is keeping you awake at night the best thing you can do is get your technique analysed by a coach and spend more time in the water to build confidence.
You’re doing your wetsuit up, and the zipper comes off in your hands. Or you bend over to start pulling the slack up from your legs and the suit rips open along the seam. There are several things that can go wrong with your wetsuit which leaves you with three options. Either you swim with the damaged suit, you swim without a wetsuit, or you don’t start the race. To prevent this conundrum make sure your wetsuit is looked after well (don’t leave it out to dry in the sun, rinse it after every use, fold carefully) and make you you always get someone to do your wetsuit up for you, as this puts less strain on the zipper.
Swimming in open water can be intimidating, it’s cold, murky and deep. Throw hundreds (perhaps even thousands) of athletes thrashing through the water into the mix and you have the perfect storm for a panic attack, especially in newer swimmers but even the most experienced of swimmers have a wobble every now and then. If you’re concerned about this start at the back, and most importantly get some open water practice in before your event. If you do have a panic attack in a race, hold onto a kayak (without capsizing the poor occupant) to catch your breath and calm yourself down. In a worst case scenario they can call the rescue craft to pull you out and take you back to shore. The best way to prevent a panic attack in the first place is to get more open water swimming done, which is one of the reasons I recommend novice athletes choose a mid/late season race to give them enough time in the lakes/sea to feel comfortable during their race,
The rotation of the swimming action can cause nausea even before you bring waves into the equation. I suffer from motion sickness, but am thankfully yet to have any problems in open water, however I know friends who it has caught out badly, and they’ve ended up emptying their stomach several times during the swim, which is a nightmare for longer events as you lose precious calories. If it’s especially bad it could lead to a retirement and a trip to shore via a safety craft, but this is extremely rare. If you know you suffer on boats, taking seasickness tablets before the swim is a sensible precaution.
The longer you’re in the water, the colder you’ll get and as most triathletes have very little body fat, we can get really quite cold. I remember getting into trouble following the two mile Swim Serpentine event, and I’d been open water swimming for five years up until this point so was hardly a newbie, but a lack of time in the open water that year had left me susceptible to the cold. Most wetsuit swimmers would have to be in the water for a couple of hours to be in real trouble with hypothermia, but that’s not to say it won’t happen. Safety crews are trained to check for the signs of hypothermia, and may pull you out against your will if they see you struggling and incoherent. To prevent this, simply spend more time in the open water to acclimatise your body for the cold temperatures. Think how cold 10 degrees feels in the early autumn and how tropical it can feel in the spring, the more time your body spends exposed to cold temperatures the better you become at dealing with them.
Yes there are jellyfish in the sea, and even in the UK they can be nasty. You’re most likely to encounter them on warm days where the water is still, so it can pay to look sightly ahead of you at times to avoid the larger specimens. Most jellyfish will steer clear of a writhing mass of bodies though, and swim safety crews will do their best to remove any particularly large jellyfish (lions mane e.t.c) they spot. If you are unlucky enough to get stung, it can smart, there’s no getting around that, but there’s not a lot you can do about it other than suck it up. If the pain stops you from swimming you may need to pull out. To reduce the likelihood of this occurring you can make sure you wear a wetsuit or swimskin when swimming in the sea, as well as wearing gloves and booties where they are permitted.
A slightly left-field one, but this is the only time one of my athletes have ever failed to make it out of the water. He was suffering with mild hayfever in London, but upon travelling to Staffordshire he reacted badly to the increased amounts of tree pollen. When he started the swim a lot of the pollen was resting on the surface of the water and his throat closed up to the point he couldn’t breathe. If you know you suffer with bad allergies at a specific time of year, it may be worth avoiding lakes surrounded by large amounts of your problem pollen where possible.
Losing your goggles
Yes, it can happen! You’re swimming along minding your own business when you take a foot to the face, knocking your goggles clear off your head. You turn around to see them engulfed in a writing mass of bodies, quite possibly heading down towards the murky depths, and the chances are this will cost you a LOT of time, perhaps even causing you to miss the cutoff in a worst case scenario. To prevent this I recommend wearing your goggles under your hat, or if that causes issues, you can try one cap over your head, then place your goggles over that, followed by the race cap on the top to ensure they don’t go anywhere! Practice this in your open water training to find a combination that works for you.
One of the old adages of triathletes is to always take a spare pair of goggles to a race, as you never know when they’ll give up on you. I invest in a brand new pair before every big race (doing a couple of practice swims first to ensure they make a good seal) to reduce the likelihood of the strap or nosepiece breaking during the race, but having a pair on standby before the swim start never hurt anyone. Another reason for a new pair on race day is to avoid having to mess around with anti-fog which can burn your eyes if applied in a panic before the swim start.
Luckily there aren’t many ways you can go spectacularly wrong here, but that’s not to say its impossible…
Not performing a walk through
Once you have your transition setup do a walk through of the transition area. Start at the swim in, to your bike bag (if applicable), to your bike, and then to the bike out. I was once number 800 and placed by bike bag on the hook for 808 by accident. If I hadn’t have done a full walk through after racking and athlete 808 didn’t start for whatever reason I could have had several minutes of blind panic trying to find my bag. This also ensures you find the quickest possible route to your bike and instinctively know which direction to head in for the bike out.
Not having the right kit
It’s like one of those dreams you no doubt have (I know I do), when you get to your transition area and discover you’ve forgotten something like your bike shoes, helmet or race number. Without these you will not be able to continue your race. Ensure you avoid this by writing a checklist of the kit you need and ticking each item off as you pack them into your car. Most races have an expo for items like race belts and anti-chafe, but will have very limited stock of most big items.
Marking your bike
Finding your bike can be a nightmare, there may be thousands of them in a small space and you wouldn’t be the first athlete to have the brightest idea of attaching a balloon to your bike to make it easier to find. This is banned to prevent transition from looking like a funfair, and will be removed by the commissaires, possibly resulting in a disqualification or you struggling to find your bike as you were relying on a balloon which has since been removed. If you are taking part in a race where your bike and run kit are laid underneath your bike you can mark it with a colourful towel on the floor next to your bike.
Not putting your helmet on before you leave transition
Depending on the race they may politely request you go back to your bike for your helmet, or they may disqualify you on the spot. The rules state you must put your helmet on before you even touch your bike, however I’ve yet to hear of anyone actually getting booked for this as long as they have their helmet securely fastened on their way out of T1.
Mounting before the line
A mount line will be clearly visible on the ground, hopefully accompanied by some flag waving marshals informing you of the location of the line. Mounting before the line will likely only land you a penalty unless you really take the mickey, although it may place a bearing on future penalties if you continue to flout the rules.
If you are happy doing the flying mount then you can give it a go, however I’m not a huge believer for most events as it is marginally faster, but time gained by the speed at which you get in the saddle is offset to an extent by time spent getting your feet into the shoes and tightening them, even the best athletes are only looking at a few seconds of benefit, and while this is incredibly important in draft legal races it does carry with it an element of risk if you get it wrong and end up on the deck. Far be it from me to recommend which mount is right for you, but make sure you’re happy performing the mount of your choice and practice it in training, whatever you do don’t attempt it for the first time on the day.
Unfortunately this is the stage of a race where you put your trust in your bike and the competitors around you to reach the dismount line, and this doesn’t always work out. Some things are truly in the lap of the gods (if your pedal snaps off or someone crashes in front of you it just wasn’t your day), but some mistakes are avoidable, and with a bit of know how your day can be salvaged.
As we mount our bikes we are putting our faith in the machine between our legs to carry us home, however things don’t always go to plan. Whether it’s a puncture, a dropped chain, a seized rear mech, a pedal that detaches itself, rubbing brakes or any other myriad of things that could go wrong, you want to put yourself in the best place possible to come back from it. This means carrying everything you need as well as possessing the know how on how to fix it if things break. There is neutral support in larger events that will provide you with mechanical assistance if required, but they will not fix a puncture for you as they’d never get to the people who really need help. I recommend everyone purchases a book on bike maintenance and/or attends a mechanics course at your local bike shop. Being able to fix your chain, repair that puncture, adjust your limit screws or re-tighten your saddle if it slips can be the difference between your glorious finish or standing at the side of the road waiting for the broom wagon. Some mechanicals are terminal (snapped mech hanger, broken crank arm, broken spokes e.t.c.) and it just wasn’t your day, but a surprising amount of roadside mechanicals can be fixed with a bit of know how and a multi-tool.
You’re on a bike, so crashing will always be a possibility, it has been for as long as people have been riding bikes, and I can’t see that changing any time soon. Sometimes you can get over excited and leave your braking too late, sometimes you hit a patch of oil, sometimes another competitor takes you out, the result is normally the same, ending up on the deck with you and the bike damaged. Depending on how high speed the crash was, and how you landed, you may want to jump straight back on your bike, but please take a moment to assess yourself and your bike before you mount up again. Some of us are able to put up with a lot more pain than others, and may be able to push through where others will want to retire as soon as they see a bit of blood, but before you make any decisions test your range of motion. If you get any burning pain it’s possible you’ve broken something and it’s simply not worth the risk of continuing. Equally you’ll want to check your bike over, if the frame is cracked it’s absolutely not safe to continue. If you crash badly another competitor will inform the next marshal they see who will alert the medical teams, if you are ok but your bike is out of action or you simply want to call it a day, you can ask one of your competitors to inform the next marshal they see of your predicament. While I wouldn’t advise pushing your bike along a live race course, if you are in a dangerous position it is probably worth getting somewhere with relative safety, warning other riders of the hazard if deemed necessary. To reduce the risk of ending up on the tarmac altogether make sure you invest in quality high grip tyres, you keep your eyes on the road, and give competitors plenty of room. Don’t assume they’ll take the racing line in corners or know you’re passing them.
You come out of the water, you’re buzzing from excitement and ready to ride. You jump on the bike and fly out of transition, before long you start to feel the chill on your chest as the wind cuts through your tri suit. It then starts raining, there’s a long downhill, and you’re starting to shake now. Before long you’re on the long downward spiral of hypothermia, which is difficult to come back from. The way to prepare for this is to look at the air temperature as well as the water temperature. If the water is warm, but the air is cold, you’re going to get really cold on the bike. You also need to look ahead to the rest of the day, it may be 12 degrees and overcast when you start, but it could be up to 25 and dazzling sunshine by 1PM, so taking your long sleeve windproof jersey may be a poor choice. The way to get around this is to use layers, such as a windproof gilet and arm warmers to start with, which you can remove and stash away after you finish with them (make sure you have somewhere to store them first!). If you’re not comfortable you can’t put out the power you need, so time saved in T1 by jumping straight onto your bike may be lost as you start shivering and struggle to ride hard.
Poor bike comfort
As I mentioned above, you need to be comfortable to ride well, and if you’re shifting around in the saddle, suffering from genital pressure or otherwise unhappy on your bike you’re going to have a bad time. This is especially true for time trial bikes which can be especially difficult to get setup. There are two things you can do to avoid this, firstly make sure you get a proper (2 hours plus) bike fit and do some riding in your trisuit on the bike you’re planning to use. I made the mistake of neglecting this ahead of my most recent 70.3 and had to pull over for some respite in the last 10K as a result before eventually limping into T2 and waddling onto the run course.
Most races are non-drafting which means that if you are caught within the draft zone you will probably be slapped with a penalty. This will probably be for a few minutes, but if you are caught again you may be be disqualified. Most large events have a real drafting problem, as there’s simply not enough space on the road for everyone to leave 8M between the rider in front. The commissaires normally show a small amount of leniency as athletes come out of the swim together, but once you’re a few kilometres in you can expect a drafting penalty if you intentionally sit in the draft zone without making an effort to pass another rider. Repeat offenders may be disqualified, so don’t be lulled into a false sense of security because everyone else is doing it and keep your distance.
Nobody really knows what causes cramps, but you sure as hell know when it hits. Your legs feel like they’ve been replaced by searing hot iron bars and you’re unable to continue with any grace until it subsides. To reduce the chances of cramps make sure you ride over the distance of your event in training, don’t push too hard on the hills, and make sure you get enough salt/water. If you have a history of suffering with cramps it may be worth making sure you look up stretches which will help alleviate the issues should they occur on course.
Knee pain, back pain or any other number of issues can flare up with no warning during your ride, and really make you suffer. If the pain is mild and it’s your A race then you might want to crack on, but if it’s more severe or you have a much bigger race in the near future and it’s not disappearing it may be better to cut your losses and call it a day. There isn’t always an obvious answer for this, it could be the sheer amount of time spent riding without stopping, the amount of climbing, your race setup, your seatpost slipping in transit, any number of possibilities. You know your body best and whether you are able to continue, but remember you still have the run to go…
This can be either a result of high humidity or direct, relentless sunlight. In these situations you may want to choose your helmet carefully and consider a more ventilated model, furthermore make extra sure you’re getting enough water and electrolytes, as well as moderating your effort, especially on the climbs. Failure to do so can involve in your core temperature peaking, heart rate red lining and you digging yourself a huge hole.
The simpler of the two transitions, but you’ll be tired and can’t let your attention drift.
There is a much greater risk of hurting yourself with a flying dismount than a flying mount, so ask yourself whether it’s really worth the risk. Make a careful assessment of the speed you’re travelling at and whether your legs can keep up with your current speed before you commit. If in doubt, dismount normally.
Dismounting after the dismount line
This will land you a time penalty, which if combined with a drafting penalty may result in you being disqualified after you finish the event. The line should be marked with a line and marshals holding flags, just make sure you slow yourself quickly enough to get your feet on the ground before the line.
Racking your bike in the wrong space
While you may not be able to receive an outright penalty for this (depending on the race), an angry competitor who finds your bike in their space may remove your bike and place it somewhere where it could be deemed to cause an obstruction resulting in a penalty. Take the time to find your racking space rather than panicking and placing it in the wrong spot.
Once you’re off the bike a huge number or variables have been removed, now it’s just you and your body against the clock, although over long distance racing this is where the majority of athletes tend to falter as the efforts of the swim and bike take their toll on their body.
Went too hard on the bike
So, you may have got a bit carried away on the bike, overtaking dozens of people, flying up the hills, soaking up the scenery, your legs felt good and it’s a race after all isn’t it? Now you’re on the run and struggling, you can’t pick your feet up, your quads are heavy, you’re trying to shake them out, but you can’t change out of plod mode. You’ve gassed it on the bike and are now paying the price as those who you made a point of overtaking earlier now fly past you. Eventually your run turns into a walk and perhaps even a shuffle as the time cutoff looms behind you. Pace the bike well and with the run in mind to avoid this, going as little as 3-4% over target on the bike can have devastating consequences on the run. Nobody cares about your bike split when you’re sat at the side of the road with your head in your hands.
Running when you should be walking
You will in most cases have at least six hours and thirty minutes to complete the marathon, even if you leave T2 just as the cutoff kicks in. The average walking speed for your standard member of the public is 5KM per hour, so you should be able to cover the distance even if you were to walk the entire thing. I obviously wouldn’t recommend this as you want to do yourself justice, but it goes to show that you could probably power walk the run course and still make it home within the cutoff. This means you can afford to take walking breaks during the run, walking the vast majority of it if you need to. If you’re determined to run the whole marathon this can result in you actually moving slower and increases the risk of you cramping or another injury rearing its ugly head and sending you back to the medical tent in an ambulance. I’m sure you want to be able to tell your friends that you ran the whole marathon, but you really don’t want to have to explain to them how you failed to finish because you wouldn’t walk out of pride.
As anyone who has spectated at an Ironman will be able to tell you, the marathon course is littered with people on the side of the road clutching their calves or desperately trying to stretch their quads out with a face that suggests they’re undergoing surgery without anaesthetic. The cramps have struck and their race is in tatters. It’s incredibly difficult to come back from this, it may well be the beginning of the end. Nobody really knows what causes cramps, but they have been linked to poor hydration and a lack of salt, so making sure you stay topped up will help reduce the chance of you encountering any problems. A strong running background will help as well, as your body will be used to the demands of running long distances and less likely to rebel.
Your stomach can only digest so much at once, after which it struggles to empty your stomach at the rate you may be adding sports drinks, gels, nuts e.t.c. and you can end up feeling very bloated as a result, especially as it’s tougher to digest food while running. You may have been on a diet of non solids for ten hours by this point and your digestive system may well be starting to play up by this point, however there really is no way to know what your stomach will be doing at this stage. Some people have intensive IBS, some people have to make themselves sick to empty their stomach, I don’t want to put you off but a lot can go wrong so it’s a good idea to fill your special needs bag with a variety of things you think you might want/need, just like you were packing for a weekend away and didn’t know how much food there would be at the other end. This is also why it’s important to test your nutrition during your training, to see what works well and what doesn’t. It’s worth pointing out that low sodium levels have been linked to low stomach emptying rates as the body struggles to absorb the contents of the stomach into the bloodstream, so those salt tablets become all the more important.
There are two ways an injury can scupper your dream at the last hurdle, firstly you can line up knowing that you have an injury that will hamper you on the run, and simply hope that everything somehow comes together on the day. There’s not a huge amount that can be done to mitigate this, but going out with a run/walk strategy in mind when you start is probably the best way to manage this, and it’s worth practicing in training. The second possibility is that an injury springs up on you during the race. This could be an injury you picked up in training and thought had gone away, or it could be something totally new. When you start the run you will already be fatigued, and the longer you spend on the bike the more your muscles will be fatigued. This is true of not only the primary muscles used in cycling such as the quadriceps and hamstrings, but also muscle groups such as the hip flexors and glutes which provide us with stability when running. If you come off of a six hour ride and then run for another four hours, the muscles that are supposed to stop our knees from tracking or our hips from dropping are already exhausted and our legs move in ways they’re not supposed to. There’s not a huge amount you can do to mitigate this when you’re on the run and hurting other than start walking and hope you can make it to the finish before the cutoff. The general rule is that running on an injury when it hurts makes it worse, so you have to make some decisions here. Is this your A race? How much does the finish mean to you? What are your plans after the race? Would the potential worst case scenario (tendon rupture e.t.c.) prevent you from working? Or potentially from ever running again? These are questions only you can answer, however I would always advocate putting health before fitness or any athletic achievements.
I’m using this very broad term to cover skin issues including sunburn, chafing, blisters or any other temporary issue which can cause you significant pain or discomfort. If you have a history of chafing in areas such as your underarms or nipples then it’s wise to pack some vaseline or similar to help relieve this, but don’t apply it to your wetsuit before the swim as it will damage the neoprene, body glide is recommended in these situations. Avoiding sunburn on the bike and run can be tough as most suncream applied before the swim will wash off in the water so reapplication in transition can be wise, especially if you know you burn easily.
This may raise a laugh from some competitors, but happened to me at a very small middle distance event where upon arriving at a junction I was greeted with a signpost blowing around in the wind and no marshal. I chose to go right and five minutes later was greeted by three runners coming towards me shouting “Don’t run this way!”. This was incredibly poor by the race organisers, but if I had taken the time to familiarise myself with the course beforehand by checking the course map I may have been able to avoid the situation.
