Angeles Crest 100 Endurance Run


The San Gabriel back country retains much of the natural beauty, if not the primitive wilderness of yesteryear... Thanks largely to the foresight and capable supervision of the U.S. Forest Service and hundreds of volunteers. Picnic areas and campgrounds have been constructed with minimum displacement of the natural setting.

Those desiring to see this primitive wilderness in a single day are invited to participate in the Angeles Crest 100 Mile Endurance Run.

The 2021 race date has been canceled due the Bobcat fire and coronavirus (COVID-19). The 2022 race date is on August 6, 2022 at 5:00:00 AM/PST.


2022 AC100 is on for August 6, 2022. We will keep you informed as we get more information about the race.

We have been putting on this race since 1986. Thirty five years now! With only two cancellation from 1986-2019.  Thirty three years!  Both cancellation due to forest fires, one being the huge Station Fire in 2010.

Then in 2020 we had to cancel for the beginning  of the world wide pandemic.  And in 2021 we had to cancel for both the continuing pandemic and the Bobcat Fire.  Large section of the race is in Bobcat Fire Burn Area.The Bobcat Burn Area of the ANF has been closed to the public until April 2022.  Two Years, two cancellation!  Very difficult times! And during that time, only 5 runners dropped from the race!

Most people are fully vaccinated and have their booster shot.  In order to register in Wrightwood to run the race, all 2022 runners and pacers must be vaccinated and we recommend they have their booster shot. They will be required to show their CDC Vaccination Card with the their vaccination shots.  Masks and social distancing will be required: during registration, at the Start, during the race at aid stations, at the Finish and anytime there is a large group of  people together.  We will conduct the registration and most of the activity outdoors as the weather permits. Social distancing will be followed for any indoor activities.

In April 2022, the USFS will allow public access into the Bobcat Fire Burn Area and they will allow AC100 Volunteers to enter the Burn Area to begin clearing the trails for the race.

The area with the biggest trail damage from the Bobcat Fire is between Shortcut Saddle, Redbox, Newcomb Saddle, Chantry and Idlehour.  Most of the burn area is around Mt Wilson.  The trails above (Upper Winter Creek Trail) Chantry and below Chantry took some of the heaviest damage.  The road to Chantry is damaged about 3/4 miles from the top of Chantry where it is currently “one-way” to pass through the damaged road.  The road repair is scheduled to begin January 2021 and will take one year to complete.

The basic road to Chantry is undamaged and is passable in a singe lane.  About 3 to 4 feet of the “outer edge” of the road has collapsed under the road guard railing.  It doesn’t seem to be a “major” road damage that would take one year to repair and maybe repaired sooner.  Due the heavy damage of the trails in the Chantry area and the road damage, Chantry has been closed to the public and will remain closed for 2022.  We will have an aid station at Chantry during the race but Chantry will be closed crews and pacers, if the road is not repaired in time for the race.

USFS will allow the AC100 Trail Maintenance Program to begin clearing trails in the burn area in April 2022.  We have been clearing some of the trails that is not in the burn area on the upper PCT near Wrightwood.
