The London Marathon 2026

Take part in the world’s most iconic marathon – and fund life-saving care for people with heart and lung conditions

The legendary 26.2-mile route takes you through the heart of London, past some of the city’s most recognisable landmarks. It’s an unforgettable experience and one of the greatest challenges in distance running.

Thank you so much to everyone who has applied for a Charity place. We are currently looking through all applications and will be in touch with applicants by the end of July.

It’s £100 to register, and we ask you to raise at least £2,500 in sponsorship.

You’ll get a charity running vest, a fundraising pack, and friendly one-to-one support to help you hit your target.

Every penny you raise will fund changing equipment, advanced technology and vital research at Royal Brompton and Harefield Hospitals.

When you push your limits for heart and lung healthcare, every mile brings us closer to the answers we need.

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.
