American River Endurance Runs 2027
The American River Endurance Runs take place on April 3, 2027, with the primary route running from Folsom toward Auburn along trails that follow the American River Parkway. The event headquarters is listed as Folsom Point Boat Ramp in Folsom, California.
Three race distances are offered:
- 50 mile
- 25 mile
- 10 mile
Entry for participants includes a NorCalUltras goody bag, a technical race shirt, a handcrafted finisher medallion, Neversecond gels and Skratch hydration available on course, professional timing and results, and a post race gathering with food and a beer garden for those 21 and over.
Registration opens July 31, 2026 and closes March 29, 2027. Entry fees are tiered and vary by date and distance; current availability and price tiers are shown on the organizer platform. Per the stated policy, all standard entry fees are non refundable and non transferable. A paid Race Roster Refund Protection Program is available to cover refunds for specified protected reasons; that program is optional and handled separately from the standard entry. Registrations completed after March 21 may not be guaranteed the requested shirt size due to inventory limits.
Race services and sponsors are provided by regional partners, aid vendors, and local organizations associated with the NorCalUltras event. Visit the organization's website for the most recent information.
