The Angeles Crest 100 Mile Endurance Run has been held since 1986. It is one of the original five 100-mile races and is a point-to-point course between Wrightwood and Altadena, with elevations ranging from 1,135 to 9,300 feet. The race has maintained its original course over the years, making it one of only six point-to-point 100 milers in the United States. Runners who participate in this race will cover 100 miles of the San Gabriel mountains, encountering steep climbs and rocky terrain along the way.
