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. 

This form is now closed. All of our charity places are now filled and we are no longer taking applications.
