2026 London Marathon

We have 4 charity places for the 2026 London Marathon. Could you be one of our runners?

Why run the 2026 London Marathon for Sibling Support?

We want you to run the London Marathon in support of us! Why? Because without your support, we couldn’t continue supporting thousands of bereaved siblings across the country and help them to understand and manage their grief.

We want you to enjoy the journey of raising funds for Sibling Support, training for the London Marathon and taking part in the event itself. That’s why we’ll be with you every mile of the way.

Because you have committed to supporting our work, we’re committed to:

  • Set up your dedicated fundraising page using Enthuse!

  • Send you a fundraising pack, including a Sibling Support running vest and protein snacks

  • Promote your run on our social media pages - sharing your fundraising page, telling your story and cheering you on!

  • Help with hints and tips that others have found useful to raise funds and train for a 26 mile run!

  • Let you know how your fundraising makes a difference to our work - we’re committed to making sure you know how your hard earned fund raising has made a difference to bereaved siblings. We’ll keep you updated with quotes and feedback that we receive from bereaved siblings and our mailing list newsletter - telling you how we’ve spent your money.

When does our application window open?:
