The BOLDERBoulder 10K is one of the most iconic and celebrated road races in the world. What began in 1979 as a small Memorial Day run among friends has grown into a global event, attracting over 50,000 participants and more than 100,000 spectators each year in Boulder, Colorado.

Recognized by Runner’s World as “America’s All-Time Best 10K,” the BOLDERBoulder combines elite athletic competition with a uniquely inclusive atmosphere. Runners, joggers, walkers, and wheelchair athletes of all ages and abilities come together from across the globe to take part in this unforgettable experience at the foot of the Rocky Mountains.

The race is known not only for its scenic course and energetic crowd support, but also for its innovative wave start system, allowing participants to run alongside others of similar pace. The event culminates at the University of Colorado’s Folsom Field, where a powerful Memorial Day Tribute honors the service and sacrifice of the U.S. armed forces.

More than just a race, the BOLDERBoulder is a celebration of fitness, community, and national pride—an event where every participant is invited to feel what it means to be “BOLDER.”
