50k Relay

When: The 2022 race has been cancelled!

Where: The American River Parkway, Sacramento, California

Race Director: Meghan Canfield

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 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!

Team USA has been successful on the world stage for some 20 years, typically achieving podium status as a team and usually one or 2 runners placing in the top 10 in the world. I personally have been a member of Team USA’s 100k team nine consecutive times, and the experience and pride of representing USA at the world level is incomparable. Training for a road 100k is challenging in that one needs miles and miles of paved surfaces, and the American River Parkway not only provides that, but also allows for the ability to run uninterrupted loops by utilizing the many bridges that cross the American River.

The funding for sending our teams to the World Championships does falls short and our athletes typically pay out of pocket or rely on some travel stipend from their sponsors. This lack of full sponsorship to represent our country has a negative effect on the depth of the teams. Therefore, half of the proceeds of No’to’mom 50k and 100k races will be donated to those teams to defray the athletes’ personal costs. The other half will go to the American River Parkway Foundation whose mission is to support the preservation and enjoyment of the American River Parkway by fostering environmental education, stewardship and volunteer opportunities.
