Where is the meeting point for my stage?
We're located at Potters Fields Park. You won't miss us!

Will the relay run on time?
It is the joint responsibility of all runners to keep the relay running to time. Please do everything in your power to prevent delays. We’re all relying on you!

Kit List

When you’re part of a tribe this awesome, it feels great to wear the uniform.

To get you off to a flying start, we're providing each of our runners with an official London Relay t-shirt! You’ll be sent your t-shirt in the post prior to your stage or be able to collect one from our Relay Hub at Potters Field Park.

We have a gear store coming soon, so if you want to get some more great kit, you’ll be able to soon!


Can I bring friends and family to cheers me on?
Absolutely, the more the merrier! Let's make these baton handovers the best experiences ever!


Become a volunteer marshal -

Whether you’re already booked to run, or don’t feel like running yet want to get involved in the City Relays’s mission to unite London, we invite you to become one of our volunteer marshals.

Volunteer marshals will be based at the Relay Base Camp, next to City Hall, where the baton is handed over roughly every hour. As a marshal you will be part of the core team.

Interested? Sign up to receive the briefing doc and book onto the rota...


Do I have to fundraise as well?
There is no compulsory fundraising target but this is a fundraising event and we’d love for you to raise funds for our charity partner The Running Charity.

Does the £20 entry fee go to charity?
The entry fee goes towards paying for the cost of the event. 100% of the money you fundraise from your profile will go straight to The Running Charity.

Should I get the media involved?
Sure thing! Get in touch with your local paper, radio and TV stations and tell them what you’re doing and why. And, if you’ve got contacts who can help put the London Relay on the national news agenda too - terrific!

What if I find I am unable to run my stage?
You must notify the organisers immediately by emailing [email protected] with the subject line ‘URGENT: I CANNOT RUN MY STAGE’. If you are the lead runner on your stage and no other runners have signed up to join you, please do your best to help find a replacement runner. We regret that no refunds on registration fees can be given.

Who can run?
Anyone can run, provided you are able to maintain an average pace of 11 minutes per mile for the duration of a stage. 5k group stages are open to everyone regardless of average pace! U18s must run with a responsible adult and have signed authorisation from their legal guardian.

    A group of our team went down for the 7pm leg of the race. It was a warm summer night which made it fun to run a lap on the Thames before passing the baton onto the next group. The Tower of London and surrounding area was good to grab drinks and food afterwards.

    I definitely found my evening slot better than the mid-afternoon one, just because of all of the traffic, but overall I couldnt have enjoyed the event more

    The atmosphere and the helpers were so incredible, its my second year of coming to this event and it was just as great as the first!

    Great event! Lovely route by the Thames and the marshals were very friendly and helpful. Feels amazing to be part of such a big thing logistically, and even better that it's for a charitable cause! Will definitely do it next year again.
