About this race
The BOLDERBoulder community begins with a "BB10K WEEKEND TAKEOVER AT RUNNERS ROOST BOULDER," providing chances to connect with other runners. This gathering in Boulder acts as a prelude to the main event, building camaraderie before race day.
During this takeover weekend, participants can complete "in-person registration saturday" for the BOLDERBoulder race. The event includes a distinctive feature "inspired by an IndyCar-style pit," creating a unique race experience for participants. This element distinguishes the BOLDERBoulder.
