Boulder County, Colo. - BBSC Endurance Sports is holding the TriBoulder Duathlon & Triathlon in Boulder County on Saturday, July 24, 2021. View the course maps online or below for the area of the race, which starts and finishes at the Boulder Reservoir. All roads on the course will remain open during the race.

The first race will start at 7 a.m. on Saturday. Riders will be single file and spread out, and all cyclists will be off the road by 12:30 p.m. A sweep vehicle will follow the last cyclists and alert the police and course marshals along the way so that traffic can return to normal as soon as possible.

If you are traveling through the area during the event please pay close attention to the Boulder County Sheriffs, Colorado State Patrol and the volunteer traffic marshals who will be helping to make this a safe situation for everyone involved. When passing a bicyclist, motorists must allow at least three feet of space between their vehicle and a bicyclist. To pass a bicyclist safely, drivers may cross a double yellow center line when oncoming traffic is clear.
