The London Triathlon is the world’s biggest multisport event, attracting thousands of athletes year on year. Its location in one of the world’s largest cities and beginner friendly nature makes it very popular for those looking to compete in their first event, while the flat, fast nature of the course also appeals to PB hunters.
There are multiple distances available:
Super Sprint: 400M swim, 10 KM bike, 2.5KM run
This distance is ideal for those just looking to dip their toe into the world of triathlon, there are limited spaces available for this distance compared to the others so it’s worth ensuring you get your entry in soon to avoid disappointment.
Sprint: 750M swim, 20KM bike, 5KM run
Very popular with first timers, this is a challenge in endurance in its own right. Most people will be looking at somewhere between 1:20 and 2:00 for a finishing time in this distance, so it’s far from a sprint in reality!
Olympic: 1500M swim, 40KM bike, 10KM run
This distance gets its name from its inclusion in the Olympic Games, a true test of endurance but without getting silly as with the Ironman 70.3 and full Iron distance events. The winners may go just under the two hour mark, with most people coming in somewhere between 2:20 and 3:10. There is a separate wave for those who can go under 2:30 to allow them a clearer, less congested course.
Olympic Plus: 1500M swim, 80KM bike, 10KM run
For the strong cyclists out there, this event isn’t too far removed from a half Ironman distance, and is a good stepping stone for those nervous about the step up to 70.3.
Getting to the start of the event can be a bit of a challenge due to the road closures for the event, especially on the Sunday where the road closures are more extensive, as a result I highly recommend you take public transport to the start if based in London, or find yourself a hotel close by if you are travelling from afar. The DLR technically has a limit on the number of bikes that are permitted on each train, but I’ve never heard of anyone enforcing this during the triathlon weekend.
Make sure you arrive at least two hours before your wave starts where possible, this allows you time to set up your transition area, collect your number, mark up your bike, get changed into your wetsuit, make multiple trips to the toilet and still be there 20 minutes before your swim start.
Ensure you take time to watch the briefing video and familiarise yourself with the layout of transition area to save you valuable seconds during your race as the clock doesn’t stop between sports!
The swim is held in the London Royal Docks, which isn’t as dirty as it looks or sounds! The docks have long been abandoned and the water quality improved dramatically in the last 15 years with the installation of a filter at the intake point. NOWCA run swim sessions most days at the west of the docks and I have spent several hours in the water coaching sessions without ever falling ill, so the likelihood of you picking something up during a race are incredibly low, just try to avoid swallowing any water.
Wetsuits are compulsory for this event, while they don’t give an explicit reason for this I believe it is due to the large mixture of abilities in the water, so make sure you have a suit ready to go as there are none available to hire on the day. As of the 2018 edition, if the water temperature is over 25 degrees wetsuits will be banned and athletes will instead be forced to swim with no wetsuit and use a tow float instead. To my knowledge this has never occurred in the history of the race, but given the summer we’re experiencing at the time of writing it’s not out of the realms of possibility.
When you arrive in your swim pen you will be given a briefing on the course and any updates on the weather/conditions, as well as a few chants to get you fired up. Once you walk outside and down the steps you will find yourself on a floating pontoon, and you can enter the water however you like, whether you prefer to dive, jump or tentatively lowering yourself in. You can be waiting for quite some time if you’re one of the first in the water, so if you’re nervous hang towards the back to avoid time spent treading water.
The swim course is as simple as can be, a one lap clockwise loop dependent on the distance that you are swimming. Make sure you start on the right to shorten the distance to the first buoy, and start towards the back if you are feeling nervous or are a slower swimmer to avoid getting swum over, which is an unpleasant as it sounds.
Once you climb yourself out of the water you have to remove your wetsuit, which there are wetsuit strippers on hand to assist you with. Your suit will then be placed inside a plastic bag and you will be pointed in the direction of the stairs that lead you back up to transition, bagged wetsuit in hand.
The reason for removing your wetsuit is to avoid getting water all over the stairs which will create a slipping hazard, in years gone by I know they placed some hessian sacking on the steps/floor on the way into transition, but this didn’t stop people stacking it spectacularly as they ran to their bike so be careful, especially if you are experiencing some dizziness after the swim.
After mounting your bike and pushing it to the mount line you will be saddle up before being sent down a ramp to ground level where you will commence the longest of the three disciplines.
The course varies depending on the time and the day you are racing, on the Saturday you will be on a much shorter course while on Sunday the course will be longer, going all the way out to Westminster if you are lucky enough to be heading out first thing.
The course is fast and flat but technical in parts due to the amount of roundabouts and 180 degree turns. I believe this has improved since I last did the event, but it’s worth keeping your wits about you on course.
The biggest factor to remember is that even though it’s closed roads doesn’t mean you can switch off, if anything it means you have to keep your wits about you even more as you will be sharing the course with a large amount of cyclists, some who may be riding in a very unpredictable fashion. Ensure you always ride on the left and check over your shoulder before any change of direction. If you hear a call of “right!” that means a rider is about to pass you on your right and this is a polite reminder to hold position or move over to let them past. Also be wary when taking corners of riders going around the inside or outside of you, hold your line and avoid erratic movements to enjoy your ride.
After you complete the bike your legs will already be tired, but it’s time for the most physically demanding discipline, the run!
The run course is 2.5KM long and absolutely pancake flat, however it is also incredibly busy as hundreds of athletes are crammed into a 2.5KM stretch of tarmac and concrete. Things have improved in recent years with a simple out and back course rather than the twisty narrow course previously used, but you may still find yourself having to weave around and sharpen your elbows to fight your way through the crowds. This is the only run course where I’ve never been overtaken by anyone, primarily as many are competing in their first triathlon and are starting to run out of gas and walk portions by this point. If you are a stronger runner be prepared to do a bit of dodging and weaving to hold your pace, if you are starting to struggle then stay to the left of the course to allow faster athletes past.
The run starts and finishes in the Excel centre with previous years including a 200M section inside the exhibition hall itself so GPS struggles, but the course comes up considerably shorter than advertised, especially at the 10K distance, I believe the distance is much closer to 9KM in total, although as I haven’t competed since 2015 this may have been addressed.
Once you cross the line you will find yourself in the finisher’s area where you will receive your medal, you can have your photo taken, pick up some alcohol free beer and relax for a bit before you make your way back to transition to collect your belongings.
If this is your first triathlon you may need to brush up on some basic British Triathlon Federation (BTF) rules to avoid any penalties/disqualifications. I’ll run you through some of the most essential rules to avoid embarrassment:
Drafting is the act of riding behind another cyclist and gaining an advantage in doing so due to . Different races have different drafting zones but at London they have a 10M drafting zone behind each competitor you are not allowed to enter unless you are overtaking. If you are caught gaining an advantage in this way you can expect a time penalty or disqualification.
Helmet on before touching bike
Not only are helmets mandatory, you must have your helmet on your head and fastened securely before you even touch your bike, not doing so can result in a time penalty, and riding with an unfastened helmet is a good way to get yourself disqualified.
Ok, so this goes without saying I hope, but most importantly this extends to keeping your torso covered, so if you have a full length zip on your trisuit you can’t run with it open if it gets hot.
Bike in good working order
This should go without saying, but if you pull a rusty bike out of the shed and wheel it down to the Excel, they won’t allow it on course. While it doesn’t have to have the top components and a thorough safety check, they will check that the brakes are in good working order and the handlebars have plugs on them to avoid injury. If they see anything else that concerns them they may run it past a BTF referee before letting it out on course.
Hopefully this has given you a good idea of what to expect and will ease the pre race nerves. Whether this is your first triathlon or you are taking part in an elite wave, I wish you the very best of luck with your race!
