What began in 1979 as a dream to gather a few hundred friends for a Memorial Day run through Boulder has become one of the largest 10K races in the country—named America's All-Time Best 10K by Runner’s World. Today, over 50,000 participants and 70,000 spectators come together to celebrate with competition, community, and patriotic tribute.

The unique merchandise we create exclusively for our participants reflects the heart of the BOLDERBoulder—thoughtful, original, and rooted in community—and serves as a lasting reminder of a RUNbelieveable race day.
