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 entry. 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 are already entered in AC100 or declines an entry, the spots will roll down no further than 4th place. If you’ve met the requirements at one of these ultramarathons, or if you’d like to add your race to the Sterling Silver series, please get in touch with us.
