In 1979 we dreamt of attracting a few hundred of our friends to race though the streets of Boulder, Colorado to celebrate Memorial Day with our families. Fast forward almost 40 years and the Bolder BOULDER has grown to become one of the largest and most highly acclaimed 10K’s in the world.

Almost 1.2 million runners, joggers, walkers and spectators of all ages have gathered over the years to create a spectacle that defies description. Olympic medal winners and hopefuls, grandmothers and kids, running enthusiasts and one-race-a-year guests from all over the world come together at the foot of the Rocky Mountains to form one of the sport’s truly unique events. Each year we host 50,000+ participants and 70,000+ spectators at Folsom Field for what we like to call the biggest and best Memorial Day Party on earth.

The Bolder BOULDER is still locally owned and operated, and our dream continues. This event has taken on a life that we never quite envisioned, and it rewards us every year beyond measure. We hope you will join us to celebrate fitness, our country and this great state of ours, Colorado.
