Pre-Event Day Questions

When is the London Duathlon taking place?

The London Duathlon will take place on Sunday 5 September 2021.

Where is the London Duathlon taking place?

The London Duathlon is taking place in Richmond Park, south-west London. You can find more information and the route maps for all of the different challenges here.

How do I enter?

Entries into the 2021 London Duathlon are now OPEN - click here to register your place today. Due to deferrals carried over from 2020, there are very few places remaining so secure your place as soon as possible to avoid disappointment. 

How do I guarantee a place?

There is no specified closing date for entries, but some categories may fill up faster than others. If you go through the online entry process and make payment, you will be guaranteed a place.

How do I know that I am entered into the event?

You should receive an email from us confirming your payment for the challenge you’ve entered.

If you are unsure that you are entered into the event, follow the procedure below:

  1. Log in to your account here, using your email address and password.
  2. Check to see if you received a confirmation email from us. If you have a confirmation email, then you have a place in the race.

Note - you may not be receiving any emails from us even if you are entered. This can be for a number of reasons:

  • You provided us with an incorrect or out of date email address
  • The emails are being directed into your junk folder
  • Our emails are being rejected by your email server
  1. If the entry fee has not been taken from your account, then you are not entered. 
  2. If you have been charged the entry fee but have not received any emails from us, please contact us. We will respond to let you know whether you are entered or not. If you are concerned that you aren't entered into the event, please do not leave it until the last minute to query it.

Can I change the race category to which I am entered?

Yes you can make changes, but all changes must be made before the closing date of registration. After this deadline we will be unable to make category changes to your entry.

What is the age limit for entrants?

You must be at least 18 years old on the event day to take part.

You have got have my age group wrong.

Your age group is based upon the date of birth that you entered. Note that your age group is determined by your age at 31 December of the race year and not your age on race day (in accordance with BTF rules).

I am unable to race, can I have a refund or transfer my place to next year?

Unfortunately we cannot offer any refunds or transfer places to next year. There are a great deal of costs involved in staging an event of this proportion, such as paying for staffing, infrastructure, road closures and medical cover, all of which aren’t recoverable.

However, new for the 2021 event we will have a Covid Guarantee - please refer to Section 5 of the Terms & Conditions for more information.

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.  

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 member's details are required at registration. Failure to do so can result in the team being disqualified.

How do I compete with friends / family?

If you are participating in the team relay challenge, you will be able to enter a team of two or three people. You will be offered the opportunity during the entry process to add a team name to your form. Then you’ll be asked to provide names for two other team members, as well as more information related to the type of activity they will engage in for the London Duathlon, their date or birth and emergency contact numbers on their behalf.

Please note that entering as a group WILL NOT secure you the same start time. This is to enable one person to pay for multiple entries. Please note that once race numbers and start times have been allocated, we cannot, under any circumstances, accept requests to race together.

My address / telephone details are no longer up to date. How do I change them?

Log into your account here using your email and password to edit your details. There is information you cannot change, such as your email address. Please contact us if you need to change this. If you have a problem logging in, please contact us.

I have entered the race. How / when do I find out about the race day?

There will be plenty of information published about the London Duathlon on our website and social media channels in the build up to event day. Furthermore, your race pack, including your race numbers and race instructions, will be posted out to you two weeks before the event.

When do I receive my Race Number and Race pack?

Race numbers, bike and helmet stickers, electronic timing chip and security band will be posted to participants two weeks before the event. If you have not received your race pack by the week before the event, please email us on

Event day questions

How do I get to Richmond Park?

Our travel advice page will be available in advance of race day.

Is parking available in Richmond Park?

Yes, there will be limited race day parking available in Richmond Park. We will be in touch with all participants around 6 weeks before race day with the chance to purchase a first come first served parking space.

When do I get my race pack?

Your race pack will be sent out in the post in the weeks leading up to the event.

What do I get in my race day pack?

Participants will receive an official race number, bike and helmet stickers, electronic timing chip and security wristband in their race pack. 

What time should I arrive?

You should arrive 60 minutes before your start to get your gear set up in the correct row in transition before warming up and making your way to the start line. 

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 music 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. Furthermore, no mobile phones or MP3 players are allowed to be used in transition or while you are racing.

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.

Are disc brakes and disc wheels allowed?

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