Angeles Crest 100 Mile Endurance Run

Angeles Crest 100 Mile Endurance Run, held since 1986, is a 100-mile point-to-point trail race from Wrightwood to Altadena in the San Gabriel Mountains north of Los Angeles. Runners tackle steep climbs and rocky terrain along a course ranging from 1,135 to 9,300 feet, preserving much of the original route and making AC100 one of six point-to-point 100-milers. It offers a wilderness backdrop supported by volunteers and the U.S.

Forest Service, with training runs and trail work days. For 2026, the course bypasses Chantry Flats, finishing at Altadena via Mt. Wilson, with lottery and finisher awards including buckles and plaques. Visit the organization's website for the most recent information.
