Nanny Goat

Nanny Goat runs 100 laps of a flat, 1-mile dirt-and-grass loop on the Sexton family's private horse ranch in Riverside, California — orange groves overhead, horses nearby, a stocked aid station every lap. The 2026 edition is the 17th annual, placing the founding around 2010. There is no elevation, no navigation, no technical terrain; the challenge is purely mental repetition and pacing. Sub-30-hour finishers earn a buckle; sub-24-hour earns a special buckle. The 100-miler runs alongside 3-, 6-, 12-, and 24-hour events on Memorial Day weekend.
