Boulder County, Colo. - BBSC Endurance Sports is producing the Tri Boulder triathlon on Saturday, July 20, 2024. The race starts and finishes at Boulder Reservoir.

Westbound Jay Rd. will be closed on Saturday from CO 119/Diagonal Highway to 51st St. from 7:15 to 11:30 a.m. All other roads involved, including eastbound Jay Rd. from 51st St. to CO 119/Diagonal Highway, will remain open throughout the event.

The first race will start promptly at 7:15 a.m. with the cyclists hitting the road at approximately 7:25 a.m. Riders will be single file and spread out, with the last cyclists leaving Boulder Reservoir at approximately 8:30 a.m. 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 events, please pay close attention to the Boulder County Sheriff’s Deputies 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.
