97.3 KBCO is the official BOLDERBoulder station! When signing up be sure to select "Join Team KBCO!" in wave placement details. The BOLDERBoulder is Colorado’s premier community event and the best way to kick off summer. The adrenaline, excitement, and anticipation at the start line. The live music and entertainment at every turn along the course. The thrill of entering Folsom Field with cheers from tens of thousands of screaming fans rooting for you. The parachuters, the fly over, and the Memorial Day Tribute.
