Jigger Johnson Ultras

Jigger Johnson Ultras is a weekend of trail races in the White Mountain National Forest based in Waterville Valley, New Hampshire. The event features multiple distances with long, mountainous courses and substantial elevation gain:

  • 108 miles (100 Mile)
  • 58 miles (50 Mile)
  • 20.1 miles (20 Mile)

Courses use forest trails, ridge lines, sections of road, and exposed mountain terrain. The 100 Mile is an out-and-back to the South Moat area and lists about 29,000 feet total elevation gain; the 50 Mile lists about 16,000 feet; the 20 Mile lists about 5,900 feet. Parts of the routes are unmarked, require following GPX files or maps, and include long stretches without aid stations.

Mandatory gear is required and checked before the race. Common required items include a minimum of 2 liters of fluids, a water filter, mapped GPX file, emergency blanket, headlamp and spare batteries, rain jacket, warm layers, cell phone and extra battery, compass or GPS, neon reflective vest for road sections, and a basic first aid kit. Qualification requirements vary by distance: the 100 Mile requires a recent 50-mile or similar mountain effort, the 50 Mile requires a recent 50 km or similar mountain effort, and the 20 Mile has no formal qualification.

Crew access is restricted at remote aid stations; pacers may be allowed from specified aid stations and must carry required gear and complete a gear check.
