Stage one of the San Dimas Stage Race begins Friday on Glendora Mountain Road with the uphill time trial.
This portion of the race, starting at 8 a.m., will be a difficult 4.25-mile climb up the famous mountain road.
The race, sponsored by the Southern California VELO Cycling Club, is scheduled for March 22, 23, and 24.
The San Dimas Stage Race was born as the Pomona Valley Stage Race in 2000, a 3-day stage race that was the brainchild of Rick Thomas, president of SC Velo at the time, according to a race history on the cycling club’s website.
The event has since been led by several cycling members who have grown the race to what it is today, race organizers said. For details on the race, check on the Southern California VELO Cycling Club’s website.
