Ride Start Time

Please plan to start your ride between 6:00 a.m. – 7:45 a.m. All riders MUST be on the road by 8:00 a.m. We encourage riders to begin early to avoid Colorado’s traditional afternoon mountain thunderstorms and highway traffic.

Colorado State Patrol does not permit anyone to start before these posted times, however, if you find yourself riding before first light you must have both a front and backlight on your bike.

Vail Pass Sags

If you are unable to make it over Vail Pass, our sag vehicles can take you to the top of Vail Pass or Copper Mountain. In order to pick up the sag, please stop at the parking lot at the East Vail exit, before the aid station on the base of Vail Pass.  

SAG Support

Sag wagons will be available to assist riders who are experiencing mechanical trouble or those who become too fatigued to finish. Please be prepared to handle your own flats and minor repairs.

Private SAGS

For the safety of all riders, private sag vehicles are NOT permitted on the course.
