Can I guarantee the same wave as a friend, family, or work colleague?  

To ensure you race with friends, family, and work colleagues you need to choose the same race category. You will also need to request the same gender race (male, female or mixed) during the registration process. Closer to the event date you will be given the option to join the same Tri-Squad. We’ll try our best to ensure you and your Tri-Squad are in the same wave, but this is not guaranteed.

How can I book accommodation for the events?  

For event specific accommodation information please visit the ExCeL Centre website.   


How do I get to the Excel Centre?  

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.  


What time do I need to arrive?  

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.  


Do I need a wetsuit?  

A wetsuit is compulsory and it is your responsibility to ensure you have one on race day. The wetsuit will not only keep you warm, but will also help you swim faster as it provides you with extra buoyancy.  

Wetsuits must be worn up to 25°C. Should the water temperature exceed 25°C wetsuits are not permitted and changes to the event may be made at the organisers discretion.  

Surf and shortie wetsuits are allowed, but these are totally different to a triathlon specific wetsuit, which is designed for swimming and fits like a second skin.  


What do I wear underneath my wetsuit?  

We recommend that you wear a tri-suit, but it is not compulsory. Regular sports kit is fine over a swim suit.  


Can I listen to a personal music player whilst racing?  

No. You will be unable to hear other competitors or the marshals when you are wearing one and consequently pose a threat to others.  


How can I be sure that the water will be safe to swim in?  

We conduct numerous tests right up to the race day itself to ensure that the water is safe to swim in.  


Can I use any stroke on the swim?  

You can use any stroke you desire except for backstroke as this replicates the sign of distress.  


Can I use tri bars on my bike?  

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.  


Is the race draft legal?  

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.  


Where do I find more information on rules and regulations?

Is water available during the races?  

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.  



How can I find out my finish time? 

Provisional results will be available in our LimeLight Sports Club app, on our website and if you have inputted a British mobile number, they will be texted to you.
