Boulderthon

Experience the magic of Boulderthon presented by lululemon, recently recognized by USA Today as one of the Top 10 races in the U.S. and one of the fastest-growing races in the country.

Boulderthon offers distances for everyone: a full marathon, half marathon, the 10K presented by Cheribundi, the Heart to Heart 5K by BCH, and the Boulder Country Day School Kids Run. The full and half marathon courses feature sweeping views of the Flatirons, Boulder Reservoir, Table Mountain, and Haystack Mountain, finishing downtown on Pearl Street. The 10K runs through Boulder's scenic streets to the same iconic finish; the fast, flat Heart to Heart 5K includes a $40,000 prize purse.

Whether it's your first 5K or your next PR, Boulderthon brings big-race energy with the charm of a mountain town. Crisp fall air, golden leaves, and a Pearl Street finish make it a race like no other. In its fourth edition Boulderthon drew nearly 10,000 runners from all 50 states and 22 countries.

Benefiting the community, the event generated an estimated $22.8 million economic impact locally and regionally. Outside race weekend the organization runs volunteer and environmental adoption efforts, free year-round community events, and a no-cost bib program to promote accessibility to racing.
