2026 - 4 & 8 Hours of Temecula and E-bike Race

The 4 & 8 Hours of Temecula is a mountain bike race held at Vail Lake Resort in Temecula, California, on a Saturday in November. Participants can select either a 4-hour or 8-hour race format. An E-bike race is also part of the event. The 8-hour race is open to solo riders or teams, accommodating both individuals seeking a long effort and groups sharing the day by completing laps. The event is also known as "The Vail Grail," a name referencing its location at Vail Lake. The race offers a wide range of categories, including solo men and women, age-group divisions, single speed, Clydesdales, high school and middle school juniors, 2-person, 3-person, 4-person, coed, women's teams, and a 2-to-6-person Family Fun Team option. The Vailocity Enduro is scheduled for the next day, extending the weekend beyond a single cross-country race.
