Nanny Goat 3/6/12/24/100

Nanny Goat is a loop ultrarun held at a private horse ranch in Riverside, California over Memorial Day weekend, May 23-24, 2026. The course is a flat, one-mile loop on mostly dirt and grass with good footing and a trail wide enough for passing. Aid and crew support points are never more than a half mile away.

The event offers multiple formats:

  • 100 Mile race
  • 24 Hour solo
  • 24 Hour Relay teams up to four runners
  • 12 Hour solo
  • 6 Hour solo
  • 3 Hour solo

The objective for each timed event is to complete as many one-mile laps as possible within the allotted time. Relay teams that accumulate 100 miles within 24 hours receive a team buckle. Solo 100-mile finishers who complete the distance in under the specified cutoffs receive buckles; further distinctions are awarded for faster finishes. Participants in the 6hr, 12hr and 24hr events receive a T-shirt, a drop bag with running items and a medal. All runners who complete at least one lap qualify for a medal.

Camping on site is free; tent, trailer or RV camping is welcome and sites are available beginning Thursday morning through Monday morning. Registration is open with tiered entry fees and a registration deadline of May 20, 2026. No refunds; rollovers considered case-by-case. All participants must understand and follow event rules. Visit the organization's website for the most recent information.
