Sign up for our charity places for the London Marathon in 2026

The London Marathon is the ultimate running event, with an electric atmosphere and a legendary route from Greenwich Park to Buckingham Palace.

By taking on this incredible challenge for Guy’s Cancer Charity, you’ll be helping to fuel the pioneering, personalised care provided by the exceptional Guy’s Cancer team, and their ground-breaking research into the future of cancer treatment. 

Your fundraising will go towards items and initiatives like dedicated support groups for patients and their loved ones; impactful studies which are finding ways to detect cancer earlier and minimise the side-effects of treatment; and even supporting Guy’s Cancer’s leading surgical robotics programme.

How to sign up for one of our London Marathon charity places

Applications open from 27 April – 31 May 2025 via Eventbrite. You’ll complete a short form, pay a £50 refundable registration fee, and agree to our terms.

If shortlisted, you’ll be invited to a short Teams interview. All applicants will hear back by 14 July.

For more information on the following process and next steps please click through to the Eventbrite ticket page. 

How we score applications

We carefully review your answers to three key questions:

1. How much do you realistically aim to fundraise? Our minimum ask is £2,500 but we are always looking for ambitious fundraisers with ambitious targets.
2. What creative, fun and engaging fundraising methods will you use to get there?
3. Why does running for this charity matter to you? Tell us your story — whether it’s a personal connection, a life-changing experience, or someone you’ll be thinking of on race day.

We prioritise applicants who show passion, commitment, a strong fundraising plan, and a clear link to the cause.

Fundraising expectations:

• All charity place runners commit to raising at least £2,500
• Raise £500 by 31 October to stay on track
• Full support is provided: a fundraising hub, WhatsApp group, training via Coopah, exclusive rewards, and personalised guidance
• If you’re successful, your £50 fee is no longer refundable. If not selected, it will be returned to your original payment method
