London Marathon 2027

Challenge yourself with one of the world’s most aspirational events and make a lasting difference for heart and lung patients.

Take on 26.2 miles through the streets of London, passing some of the city’s most recognisable landmarks, with crowds cheering you on from start to finish.

Whether it is your first marathon or a personal challenge, you will be part of something truly amazing.

Apply for a charity place and take on this unforgettable challenge.

We have a limited number of charity places available, so please complete the application form with as much detail as possible.

If your application is successful, it costs £100 to register, and we ask you to raise at least £2,500 in sponsorship.

You will receive a charity running vest, a fundraising pack and one-to-one support to help you reach your target.

Every pound you raise will help specialist clinicians and researchers at Royal Brompton & Harefield hospitals make the breakthroughs they need to diagnose, and act, faster.

Ready to take part?

Places are limited, so we encourage you to apply as soon as possible.

Terms and conditions

Please read our T&C’s for taking part in a Royal Brompton and Harefield Hospitals Charity fundraising challenge, including the T&C’s for ballot places.

What better way to say thank you for the outstanding care my daughter had at Harefield hospital than setting myself the ultimate challenge and running the London Marathon. I feel privileged to be able to raise money and give back to the hospital that gave my daughter back to me.

Hitesh, father of Harefield patient
