Can I pass my place onto someone else?

If you are participating in an individual challenge, you CANNOT pass your place onto someone else. Each place in the race is unique and upon registration you will provide medical information and emergency contact details that are specific to you. If you pass on your Race Number, you could be endangering that person as we would have no information related to them, should there be an accident where medical attention was required.  

If you are a member of the British Triathlon Federation, you are required to show your membership card with the correct qualification in order to benefit from the £3 discount.

Teams may make personnel changes by logging back into the account of the person who registered the whole team. Changes made before the event day can be done online, otherwise an updated team members details are required at registration. Failure to do so can result in the team being disqualified.

How do I use a number belt?

A number belt is an elasticated belt that carries your race number and allows you to swap it from front on the runs to the back on the bike - it also means that you don't have to put safety pins through your clothing! You simply attach your number to the race belt and then put the race belt around you.

Can I listen to a personal music player whilst racing?

Unfortunately, we do not allow participants to race with headphones in. The safety of our participants is paramount and through wearing headphones you will be less likely to hear other competitors or marshals, which could become a hazard on route. By not wearing headphones you will also be able to enjoy the experience more and soak up the encouragement from spectators. If you are seen to be wearing headphones on race day you will be kindly asked to remove them and if caught with them during the race you will be disqualified.

Is water available during the races?

There will be a number of water stations on each run route. There will be water stations on the bike route but only for the Ultra participants - it is your responsibility to ensure that you have enough fluid to keep yourself hydrated on the bike leg.

Is the event registered by the BTF?

London Duathlon is not currently registered with the BTF but operates as an independent event covered by its own insurance policy in line with best practice in the event organisation industry. We do follow BTF Rules which can be found here.


No mobile phones or MP3 players are allowed to be used in transition or while you are racing.

Are disc brakes allowed?

Disc brakes are allowed as this is a draft-illegal event.

Are disc wheels allowed?

Disc wheels are permitted as Descente London Duathlon is a non-drafting event, however this may be amended should the Event Organiser and Technical Official decide in the interest of safety, such as high winds.
