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 2020 race date has been canceled due the coronavirus (COVID-19). The 2021 race date is on August 7, 2021 at 5:00:00 AM/PST.


To the AC100 runners: 2021 AC100 is still on.

That being said, the ANF (Angeles National Forest) is currently closed and is not scheduled to re-open until April 2022. There is a lot of damage to the AC100 trails between Idlehour and Shortcut from the Bobcat Fire.

The biggest damaged areas are on the Upper Winter Creek Trail (UWC) between Chantry and Idlehour (there are sections of the UWC Trail where large sections of trails are completely gone!) and on Rincon/Redbox Road between Redbox and Newcomb.

In order to put on this year’s race, we would have to repair all the damaged trails with large work parties of volunteers carpooling into the worksite. It would be very difficult but it can be done if the USFS allows our Volunteer Work Party of 30+ volunteers into the worksite. Gary Hilliard and his AC100 Trail Volunteers have done this before and the USFS knows it.

California and especially, LA County is currently in one the worst COVID-19 problem in the US and because of the pandemic, the USFS in LA County has some of the strictest coronavirus restrictions to avoid spreading the virus. And one of the rules is to maintain 6 feet separation in a vehicle! There is no way we can carpool and maintain 6 feet separation. There is no way we can take 30 cars into a worksite.  That’s one of the problems we are dealing with. As the current vaccine program works through our area, there may be some changes to USFS COVID-19 restrictions and with new government leadership, the vaccine program is quickly accelerating.

We are going to try meeting the District Ranger, who gives us our Special Use Permit, in early April and see if he can relax some of the restrictions and allow volunteers to repair the damage is done to the trail by the Bobcat Fire. If the trails can be safely cleared and repaired, he might give us the Special Use Permit to put on this year’s race.

When we meet with the District Ranger in April 2021, we are going to let him know that all runners are required to put in 8 hours of trail maintenance in order to run the race. Most of the runners are from Southern California and Gary and his volunteers provide over a thousand documented hours of volunteer work every year in order to put on the race. If this year’s race is canceled, all of this year’s volunteer hours will be lost.

In Retrospect: After the 2009 race was canceled due to the Station Fire we had a similar problem about accessing a closed ANF to repair trails. We talked to the District Ranger in April of 2010 about accessing the closed ANF to repair damages trails so we could put on the race. Eventually, they let us in the ANF, we did a lot of trail work and they gave us the Special Use Permit to put on the 2010 race.

This year is a bit different than 2009 because we now have to deal with COVID-19, which is making things a bit more complicated. But we are hoping that the accelerated vaccine program will change things by spring and we have a chance to put on the race.
