Welcome to the Mt. Disappointment Endurance Runs where you can experience some of the finest trails and canyons of the San Gabriel Mountains. Our course is incredibly scenic, yet strenuous and challenging. We feature fully stocked aid stations as you become part of the semi-wilderness surroundings. The final climb to the summit of Mt Wilson up the Kenyon Devore Trail will test each runner with terrain and surroundings that are truly unique to these canyons.
