2027 TCS London Marathon Application Form

In April 2027, we'd love to have you with us as part of Team CF, running for a life unlimited by cystic fibrosis for everyone with the condition. The London Marathon is our biggest annual fundraising event. We're looking for enthusiastic, hard working fundraisers ready to take on this once in a life time challenge! 

Places in the 2027 TCS London Marathon are limited for Cystic Fibrosis Trust. Unfortunately, this does mean we cannot guarantee places to people who have had a place previously with us. We want to make sure our supporters all have the opportunity to be a part in the biggest fundraising event of the year. 

If you are applying for a charity place, please can you make sure you have also applied in the ballot. This will open at 09:00 BST on Friday 24 April 2026 and close at 16:00 BST on Friday 1 May 2026. If you have taken part in previous years, don't forget to see if you are eligible for a 'Good for Age' place with London Marathon. If you are successful in the ballot, we will have more charity spaces available and we will have more runners joining Team CF! 

Please note that with every charity place, the fundraising commitment is £3,000. If you join Team CF with a ballot place, there is no fundraising target. Just raise as much as you can! 

You can find more details about entering the ballot here: Enter the ballot | London Marathon Events. 

We can’t wait to receive your applications, please take time and provide as much detail as possible.
