About This Race
The Nanny Goat 100 offers runners a unique ultra experience on a private horse ranch in Riverside, California. Race director Shelli Sexton and her family open their home for this Memorial Day Weekend tradition, where runners tackle a flat, one-mile loop course over multiple time distances: 3, 6, 12, or 24 hours, with the 100-mile buckle available for those completing 100+ miles within 30 hours. The format emphasizes accessibility and community, with support never more than a mile away and aid available every single lap. What sets this race apart is its family-friendly atmosphere and ranch setting. Runners can camp on-site among trees and fence lines, with RV parking available. The course features mostly dirt and grass surfaces with good footing and wide enough trails for easy passing. The consistent loop format means predictable pacing and nutrition strategies, making it an excellent choice for first-time ultra runners or those seeking a controlled environment for distance goals. The race has maintained its welcoming character across 17 years, with activities for families and crews.
