Lace up for this Seattle fundraiser benefiting Breakthrough T1D, a leading organization committed to funding type 1 diabetes research! You'll have multiple options to get involved, whether you're up for an 8K run or wheelchair race, prefer a 3-mile walk, want a casual 1-mile fun run, or have young kids ready for the Diaper Derby. The race gets its name from its signature course that crosses Seattle's iconic University Bridge.
