Message to Runners: The Trails of the Angeles National Forest are open after a 2 year forest fire closure. Many of the trails that were in the fire zone are not yet fully restored. If you are training and/or running on any of the trails within the burn area use caution for your own safety. The trails are in a state of repair at best and not groomed as you remember them. We also suggest possibly not training alone during this period of re-growth and rebuilding.

Welcome to the Mt. Disappointment 50K Endurance Run 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.

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.
