AC100 Communications

We are the organization of Amateur Radio leaders and operators or "Hams" for check-points of the annual "AC100" - The Angeles Crest 100 Mile Endurance Run. This is an ultramarathon, a one hundred mile trail race run every year through the San Gabriel Mountains of Southern California.

If you would like to join us in committing our knowledge and skills to the safety of the runners of this amazing race, let us put you in touch with a checkpoint ham radio leader to seek acceptance into one of these teams. We have openings for non-hams as well as FCC-licensed amateur radio operators. Contact us via The Ham Coordinator. General race information can also be found at
