About the race

Jigger Johnson Ultras takes place in Waterville Valley in the White Mountain National Forest and offers multiple trail race distances over mountain terrain in mid August.

  • 100 Mile: 108 miles, 29,000 ft total elevation gain.
  • 50 Mile: ~58 miles, 16,000 ft total elevation gain.
  • 20 Mile: ~20.1 miles, 5,900 ft total elevation gain.

The 100 mile course is an out-and-back from Waterville Valley to the South Moat area and crosses multiple named peaks and ridge systems. The 50 mile route traverses high ridgelines and summits, including three New Hampshire 4,000 foot peaks. The 20 mile course includes a long stretch without aid and a single aid station around mile 11.

Organizers require specific mandatory gear because much of the course is remote and exposed. Required items include a minimum of two liters of fluids, a water filter, a GPX file loaded to a device, a headlamp, an emergency blanket, a neon safety vest for road sections, warm layers, and a communication device. Runners must show gear at check in; missing required items results in disqualification.

Crew access is restricted at remote aid stations. Pacers are permitted only from designated aid stations for applicable races and must carry the same mandatory gear and complete a gear check. Drop bags are allowed at most aid stations and should be weather sealed. Camping is available at Osceola Vista Campground and parking is at Waterville Valley Town Square.
