The London Triathlon routes

This iconic central London event gives you an incredible opportunity to swim-bike-run on closed-roads through our amazing capital city.

All competitors will swim in the Royal Victoria Dock and run around the London Docklands, cheered on by the 30,000 strong crowd. The bike route varies depending on the distance, day and category you choose.

The infamous Olympic distance events on the Sunday have a bike route like no other! You can whizz past some of London’s most infamous landmarks including the Tower of London, the London Eye and Big Ben.

Wetsuit

The triathlon-specific wetsuits will not only keep you warm but will also help you swim faster as it provides you with extra buoyancy

Surf and shortie wetsuits are allowed, but these are totally different to a triathlon specific wetsuit, which is designed for open water swimming and fits like a second skin. You can hire or purchase a wetsuit for the event via the HUUB website (https://huubdesign.com/)

*You will be given a swim cap at Swim Assembly so no need to bring your own but googles are compulsory and aren’t provided.

Bike

Fixed wheel bikes (bikes that use the pedals as a brake) are not permitted in the race. Your handlebars must not have bare open metal ends. Please obtain stoppers to plug them before coming to the race.

BTF referee bike checks can potentially stop you competing.

Bike Helmet

A bike helmet is compulsory.

Approved cycling safety helmets of ANSI Z90.4, SNELL B90, EN 1078 or an equivalent national standard must be worn by competitors. (NOTE: a CE mark is NOT an approval mark).

*Any helmet bought in recent years will comply but check for damage which would stop it protecting you properly.

Removal of Equipment

You will be able to remove your bike from Transition immediately after racing and you must remove your bike and equipment from Transition within 1.5 hours of finishing and prior to the venue closing times.

The organisers reserve the right to remove any equipment left in transition beyond the above times. The Support Team will check the bike number against the wristband number before it is released.

*One of the biggest issues post-event is caused by people taking the wrong wetsuit from Transition, please take a few seconds to check that you have your own wetsuit, most are black and look very similar.*

Drafting

Drafting is not allowed at the triathlon – anyone caught drafting outside of the Elite field will be disqualified from the event.

The London Triathlon is a great day out for both athletes & spectators!

Family and friend are always encouraged to come down, cheer on the triathletes & help create the incredible atmosphere London is famous for. Inside the ExCeL, you’ll find a great selection of food & drink, a bar and exclusive deals from the event partners. It’s completely free for all spectators to enter the ExCeL on the day.

Swim

Spectators can view the whole of the swim course from the dock edge, next to the start
pontoon. You can access the dock edge, via the stairs or lift located on the South side of the
main hall.

Bike

Either head towards the Aloft Hotel on the East side of the ExCeL, or behind the Fox Pub
underneath the walkway to Custom House on the West side of ExCeL, for the best view of
the bike course around the building.

Run

The East Car Park is the best place to grab a spot and watch the run from. With the charity cheer marquees, loud music and plenty going on, this area has an all-day party atmosphere. Triathletes need to complete laps of the run course, so this is a great spot to high-5 your loved ones a few times.

The Finish Line

As your athlete starts their final lap, it is suggested you make your way to the finish line– it’s an electrifying atmosphere! Make sure you cheer as loud as you can as your athletes cross that all-important finish line.

    Did the Olympic Sunday in 2019

    I really enjoyed my first Olympic distance triathlon in my home town of London. Best thing is that you don't have to travel far and it's very well (!) organised with everything there what you need. Areas of improvement to me could be: 1. changing the swim course to be longer on the way out so you don't have to do that 'extra' distance at the end. Mentally I found that hard. 2. More music throughout the run course. I love music and it gives me a big boost but there were only 2 locations. 3. Compared to 2018 when I did the sprint on the Saturday there seemed to be less stalls and there was no free alcohol free erdinger at the end which I had been really looking forward to! And something good to end my review with: There was less zig zagging inside the excel on the run which was much appreciated and seemed closer to the distance it should be. Thanks and see you next year!
  • Did the Super Sprint Saturday in 2019

    Pure awesomeness! For my first triathlon challenge this was perfect. Excellent organisation and great venue. The Royal Docks was a wonderful open water swim and the support from the crowd and the volunteers for my sister and I was so encouraging! A great day out and lots of fun.

    Get there early to set your self up and view the course. That really calmed my nerves.

    Did the Olympic Relay Saturday in 2019

    This was our first Olympic distance and what an event it was, despite the early morning rain. It was well organised, the volunteers were fab and it was a superb atmosphere. We thoroughly loved it 👍

    Did the Sprint Saturday in 2019

    Great atmosphere with lots of support. It's good for beginners as the waves are well managed so that everyone merges in together and no-one feels that they are falling behind.

    Did the event in 2019

    The run had to be stopped so that a dragon boat could be ferried from the water. I managed to literally just miss it but lots of people were fucked off

    Did the Olympic Sunday in 2019

    I have completed the London Tri 4 times, the Westminster bike route is very quick but the run could do with wider sections as it gets congested.

    Did the Olympic Sunday in 2019

    This is a really well organised event with a bike route, should you chose it, that passes some of London's iconic landmarks such as the Tower of London and Westminster. ExCel Centre is a great base and a very family friendly venue for those wanting to cheer you on with easy access to the TfL network.
  • Did the Olympic Plus Sunday in 2019

    First go at the Olympic plus route, having done the Olympic a couple of times in the past. Obviously the swim is the same, measured slightly over (1.6k) on my watch, and I swim in straight lines, water slightly cleaner than I remember from previous years. The bike route is pretty cool, getting to go right up to the London Eye/Houses of Parliament etc, 3 times even. This year was quite blustery and damp which made it tougher but also slightly less visually appealing, but can't really complain. The double length does take its toll - obviously not HIM tough but it starts to feel that way. The run feels like a bit of a procession - so many people on the course at the same time going round and round the little 2.5k loop. Again tough because of the ramp up into the Excel Centre on each lap - definitely my least favourite bit of the course. However overall I'd recommend it, and the Olympic plus is a nice step up from olympic, particularly if you're a strong biker.

    Did the Olympic Sunday in 2019

    Very well organised, both communications before the event and at the venue. Everyone was very friendly. The volunteers in the water on sunday morning were amazing when I was struggling with the swim, really supportive and understanding. Thank you to everyone for making it a special day.
