Ride Start Time

Please plan to start your ride between 5:45 a.m. to 7:45 a.m. ALL riders MUST be on the road by 8:00a.m. We encourage riders to begin early to avoid the traditional afternoon mountain thunderstorms and highway traffic. Colorado State Patrol will not allow anyone to start prior to first light (5:45 am) without both front and back lights on your bike.

Vail Pass Sags

If you are unable to make it over Vail Pass, we ask that you stop at the parking lot at the East Vail exit. Our sag vehicles will better assist you, as they have a difficult time driving to the aid station at the base of Vail Pass due to cyclist congestion.

SAG Support

Sag wagons will drive the course with water and be available to assistance riders 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 allowed on the course.
