Angeles Crest 100 Endurance Run

Welcome

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.

IMPORTANT NOTICES


This year the AC100 had to go through some course changes because Obama established the San Gabriel Mountains National Monument. Dominic Grossman created this petition so AC100 is allowed to keep maintaining and using the trails in the Pleasant View Ridge Wilderness. We need 100,000 signatures by July 28, 2016. Please support us to keep AC100 running: https://wh.gov/iH2KF
