Beat The Bridge

About the Event

Beat the Bridge for Breakthrough T1D is a fundraiser for Breakthrough T1D — the leading global organization funding type 1 diabetes (T1D) research. The event consists of an 8K run and wheelchair race, a 3-mile walk, a 1-mile fun run, and the Diaper Derby for toddlers. The event is called Beat the Bridge for Breakthrough T1D because the course travels over Seattle’s University Bridge, which is raised during the race. Participants try to cross the bridge before it is raised. Those who don't beat the bridge must wait, with music and entertainment, for the bridge to come back down. After a few minutes, the bridge lowers and everyone can finish the race. For 42 years, the Seattle community has come together to help Breakthrough T1D raise funds to cure, prevent, and better treat T1D. We hope you will join us on Saturday, May 10, 2025, for the 43rd Annual Beat the Bridge for Breakthrough T1D.
