In the last three editions of AC100, Sterling Silver Ticket winners didn’t just show up — they showed out.
Wyatt Million, Michael Eastburn, Max Jolliffe, and Jian (Stella) Springer all earned their entry through Sterling Silver qualifiers and went on to win the race. Beyond the podium, Sterling Silver Ticket holders have also delivered dozens of sub-24-hour finishes, proving this path consistently draws top talent.
Earn your ticket. Prepare for AC.
Recipients are responsible for their AC100 entry fee and completion of 8 hours of Trail Work. If a top-two finisher in the races is already entered in AC100 or declines an entry, the spots will roll down no further than 4th place. Races held after August 2, 2025, count toward the 2026 race. While most Sterling Silver qualifiers are 50 miles or longer, Pacifico Ultra (50K) is included as a local exception.
If you earned a Sterling Silver Ticket at one of these races but haven’t been contacted yet, please reach out — your entry into the 2026 AC100 is guaranteed.
Race directors interested in joining the Sterling Silver series are also encouraged to get in touch.
