In 1979 we dreamt of attracting a few hundred of our friends to race through the streets of Boulder, Colorado to celebrate Memorial Day with our families. Fast forward almost 40 years and the BolderBOULDER has grown to become one of the largest and most highly acclaimed 10Ks in the world. Named Americas All-Time Best 10K by Runners World, it is the 3rd largest running race in the United States and the 7th largest in the world.
