The Angeles Crest 100 Mile Endurance Run is a point to point ultramarathon covering about 100.2 miles across the San Gabriel Mountains between Wrightwood and Altadena. The course features approximately 21,610 feet of cumulative elevation gain and ranges in elevation from about 1,135 to 9,300 feet. The event for 2026 is the 36th annual running of this race, which has been held since 1986 and is one of the original 100-mile events in the United States.
The 2026 course bypasses Chantry Flats due to wildfire and storm damage and finishes in Altadena via the Kenyon/Devore Trail to the top of Mt Wilson, then continues through Idlehour, Sam Merrill, Millard and Loma Alta Park.
