The Bolder Boulder (styled as BOLDERBoulder and previously BolderBOULDER) is an annual 10-kilometer run in Boulder, Colorado. The 2007 race featured over 54,000 runners, walkers, and wheelchair racers, making it the second largest 10k race in the US and the fifth largest road race in the world. It has one of the largest non-marathon prize purses in road racing.

The race culminates at the University of Colorado's Folsom Field with a Memorial Day Tribute with one of the largest Memorial Day gatherings in the United States. Organizers have dedicated three starting waves to current and former members of the U.S. armed forces.

On March 16, 2020, organizers of the Bolder Boulder race initially decided to postpone the race, usually held on Memorial Day, until Labor Day due to COVID-19. On June 1, organizers then decided to cancel the 2020 race entirely.

From 2002-2005, the presenting sponsor of the race was Celestial Seasonings. From 2008-2012, the named sponsor was Dick's Sporting Goods. The 2025 presenting sponsor was Runners Roost.

Many awards are given based on finish times within defined age groups. Among them is the "Ageless Wonder" category, awarded to runners who finish the 10K in less time than their age (Ex. 47-year-old who finishes in 46 minutes).https://www.dailycamera.com/2016/05/25/champions-of-all-ages-bolder-boulders-rich-database-awards-inspire-quest-to-be-the-best/

Entertainment

The Bolder Boulder race course typically features entertainment along the route, supplied by local companies and individuals. Entertainment can include belly dancers, Elvis impersonators, local bands, disc jockeys, and the Bateria Alegria percussion ensemble from the Boulder Samba School. Aside from the performers, there is often a Slip 'N Slide, trampoline and bounce house for race participants to enjoy. In addition to the official water stations provided by race organizers, there are also typically unofficial stations along the route featuring beer, liquor, bacon, cotton candy, and other foods. It is common for lines to form at these stations due to their popularity among the casual race participants. On hot days, locals often provide lawn sprinklers, water guns, and garden hoses to cool down race participants.
