Have you had your TCS London Marathon 2026 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 170 runners, aiming to raise over £500,000 for type 1 diabetes research.

Please note that this is not an opportunity to gain a  charity place, but is for people who have already secured a ballot, running club or Good for Age place.

Why join Team Breakthrough T1D?

Our support includes:

  • Dedicated support from our friendly Events team from the moment you sign up; including regular catch-ups with training and fundraising tips.
  • On-going support with your training from our professional fitness coach, plus invites to a variety of in-person and virtual training events.
  • Your very own Breakthrough T1D running top*.
  • 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.
  • An invite to join our #TeamBreakthrough community via our WhatsApp and Facebook groups.

*Order yours from January 2026 once you have raised £100 or more towards your target.

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

At Breakthrough T1D, we focus on what the type 1 diabetes community needs now and next. Globally, we break barriers to help people manage the condition and enjoy full, healthy lives.

Today, we are opening doors that were once closed by diagnosis. We lead the way to more effective solutions: connecting the brightest minds to advance treatments, influence policy, and improve access to treatments and technology for those who need it all over the world.

Tomorrow, we will make this condition a thing of the past, by accelerating research and driving innovation forward.

Sign up to run for Breakthrough T1D and help to continue to make this happen.
