Since its inception in 1979, the BOLDERBoulder 10K has transformed from a modest local race into one of the world’s most celebrated road running events. Initially attracting just 2,700 participants, the race now welcomes over 50,000 runners annually, making it one of the largest 10K races globally. Set against the picturesque backdrop of the Rocky Mountains, the course winds through Boulder’s vibrant neighborhoods, culminating at the University of Colorado’s Folsom Field. Here, tens of thousands gather to honor fallen service members in one of the nation’s most significant Memorial Day tributes.

A standout feature that sets the BOLDERBoulder apart is its comprehensive age-based recognition system. Unlike many races that award only broad age categories, the BOLDERBoulder honors the top 15 finishers of each individual age, starting from age six. This approach celebrates the achievements of runners across the entire age spectrum, fostering a sense of inclusivity and personal accomplishment. Additionally, participants who complete the 10K in a time faster than their age receive the “Ageless Wonder” ribbon and certificate, further acknowledging exceptional performances.

The race is renowned not only for its scale but also for its competitive spirit. The men’s course record stands at an impressive 27:52, set by Josephat Machuka in 1995, while Delillah Asiago set the women’s record at 32:13 the same year.  These records underscore the event’s status as a magnet for elite international athletes.

Beyond the elite competition, the BOLDERBoulder is a celebration of community and patriotism. The race features live music, enthusiastic spectators, and a festive atmosphere that embodies the spirit of Boulder. A unique aspect of the event is its dedication to honoring military service members, with three starting waves reserved for current and former members of the U.S. armed forces.

The BOLDERBoulder stands as a testament to the enduring power of community and the unifying spirit of sport. Its blend of competitive excellence, community involvement, and patriotic tribute has solidified its reputation as “America’s All-Time Best 10K.”
