Join us for some beautiful 10k loops along the No’to’mom – also known as The American River, located in Sacramento, California, near Sacramento State University. This area was home to the Nisenan tribe for centuries prior to the arrival of Europeans. Please read about the Natives of this land and consider making a contribution to their organization.

One of the motivations to host these races is to increase the awareness of an ultra-marathon type that is less well participated in than the typical trail and mountain adventure. Rather it is a time trial “feel” for the ultra distance, and specifically a race type from which the USATF selects a team for to race on the world stage at the 50k and 100k World Championships. If you’ve seen either of the Hoka Carbon X world record attempts by Jim Walmsley in 2019 and 2021, and you’ve wondered what it feels like to push evenly for 50k or 100k, here is your chance!
