Have you had your TCS London Marathon 2025 place confirmed with the London Marathon race organisers or your running club? 

Use your own place to run for Breakthrough T1D and be part of our type 1 diabetes Marathon fundraising team of around 200 runners, aiming to raise over £450,000 for type 1 diabetes research. 

Please note that this is not an opportunity to gain a charity place for the London Marathon 2025, but is for people who have already secured a place.

Why join Team Breakthrough T1D?

Our support includes: 

  • Dedicated support from our friendly Events team, including regular catch-up with training and fundraising tips. 
  • On-going support with your training and invites to a variety of in-person and virtual events. 
  • A Breakthrough T1D running vest with iron-on letters for your chosen name (once you reach £100 towards your sponsorship target). 
  • Cheering materials for your family and friends. 
  • Team photo on the morning of the marathon in Greenwich Park. 
  • Fantastic support from our cheer point on route. 
  • A well-deserved post-race reception which includes a free massage to ease those weary legs, food to recover and a glass of fizz to celebrate. 
  • A private Facebook group and Strava club for all #TeamBreakthroughT1D fundraisers. 

It’s free to join us!

With your own place, it’s easy to sign up with no registration fee and no minimum sponsorship target if you choose to run for Breakthrough T1D. We just ask you to raise as much as you can to help support our life-changing type 1 research. 

Why we need your support

Research has transformed the way we treat type 1 diabetes, dramatically improving insulin delivery and blood glucose management, but we still have a long way to go. Our cure research will give people with type 1 the ability to make their own insulin again while our treatment research aims to keep people as healthy as possible until a cure is found. Furthermore, our research on preventing type 1 would mean lifting the burden of this condition from future generations. 

We are funding research on many cutting-edge projects at world-class institutions led by renowned scientists. Sign up to run for Breakthrough T1D and help to continue to make this happen.
