Hello to all Mt Disappointment faithful and all trail runners.

As of July 13th we have reached the maximum permitted number of runners for this year's event. As a result of this, registration is now closed. We would like to thank everyone who signed up for the race and especially those who gave their time and efforts to help restore the trails after last year's destructive fires and floods.

Please note, there is one additional trail maintenance day left for this year if you'd like to help out, otherwise we'll see you on race day.

Welcome to the Mt. Disappointment 50K & 50 mile 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.

Our endurance race has both 50 kilometer and 50 mile distances. We also have a kids run just prior to the 50 kilometer awards ceremony. Our trail maintenance group maintains all the trails we use. We have t-shirts, finisher’s medals, awards, raffle prizes, and a post race meal for the runners. Have an Angeles National Forest adventure…and run the Mt. Disappointment Endurance Race.
