London Marathon: April 2025
Run the most prestigious marathon in the world and raise vital funds for Leukaemia UK.
Join the world’s most popular marathon to raise money for Leukaemia UK. Along with almost 40,000 other competitors, you will run past many of the capital’s most iconic landmarks while being cheered on by hoards of famously friendly – and noisy – spectators.
You might be an experienced club runner or this could be your first marathon. Either way, we’d love your support. We’ll help you prepare for this very special event and provide you with lots of fundraising ideas.
Charity Places
Our team for the London Marathon 2025 is now full.
Ballot Places
If you were lucky enough to secure a London Marathon 2025 ballot place, do consider running for our cause. Your support will help our vital work, and will make a huge difference. You will receive the same support as charity place runners, including receiving your very own Leukaemia UK running vest and other supporting materials.
One supporter who ran for us in 2022 said – The opportunity was life changing and came at a point in my life where myself and my family all needed a boost and something positive to focus on. You provided that Key. From the bottom of mine and my families hearts. Thank you.
