The London Triathlon consists of four race categories; super sprint, sprint, Olympic, and Olympic Plus.

The Sprint route consists of a 750m swim, 20km bike ride, and a 5km run
The Olympic route consists of a 1500m swim, 40km bike, and a 10km run

The ExCeL Centre is located in East London in the heart of the Docklands. You can get to the event by car or public transport, the nearest tube station is Custom House on the DLR line. If you visit our website you can find all of the relevant information to get you to the venue to ensure you arrive in time for your wave.
In order to set up in transition and be ready for your race we recommend that you arrive 90 minutes before the start of your wave. You then need to be at Swim Assembly point 20 minutes before your wave is due to take place, this is to ensure you have partaken in our safety briefing and have received your swim cap.
We recommend that you wear a tri-suit, but it is not compulsory. Regular sports kit is fine over a swim suit.
No. You will be unable to hear other competitors or the marshals when you are wearing one and consequently pose a threat to others.
We conduct numerous tests right up to the race day itself to ensure that the water is safe to swim in.
You can use any stroke you desire except for backstroke as this replicates the sign of distress.
Tri bars (and handlebars) must be plugged and they must be secure. There is no requirement for them to be shorter than the brake levers unlike in the elite races.
Drafting is against the rules for all but the Elite Competitors. You must not take shelter cycling behind or cycle beside another competitor during the race. You can be disqualified from the race for drafting. The draft zone is a rectangle measuring ten (10) metres long by two (2) metres wide. The centre of the leading 2 metre edge is measured from the back edge of the back wheel.
Water will be handed out on the run course and at the finish line.
There will be no water stations on the bike course - it is your responsibility to ensure that you have enough fluid to keep yourself hydrated on the bike leg.
For instant results you can click on the website and click on the ‘track my runner’. This will enable you to see all of your live results and compare them to other competitors.
