The 140 racers in the Buffalo Bill Downhill, which took place Sunday outside of Golden, were forced to stop early when a helicopter carrying a crew to film the event crashed nearby the course, The Denver Post reported Monday.
No one was injured in the crash.
Organizer Justin DuBois said the event is the state's only officially sanctioned longboard race, which involves riders in safety gear racing downhill on long skateboards, reaching speeds in excess of 40 mph.
"People skate this road, but it's not really legal most of the time," DuBois said. "I knew some pro riders, and we have such good hills. This is just about having fun with your friends and doing something that's terrifying."
