Never Summer 100Km

Jackson County, United States • 24-26 Jul 2026

Never Summer 100km & 60km

The Never Summer events are mountain ultramarathons staged from Gould, Colorado, running almost entirely inside State Forest State Park between the Never Summer Mountains and the Medicine Bow Mountains near Cameron Pass. The courses include extended high alpine ridge sections, two alpine peaks and multiple alpine lakes, and spend large portions of the route between about 10,000 ft and 12,000 ft elevation.

Distances offered:

  • 100 km (65.7 miles, ~14,500 ft ascent)
  • 60 km (39.2 miles, ~8,100 ft ascent)
  • The Double (both distances)

Terrain ranges from cross country, logging and jeep roads to established alpine trail, with sections of rough, overgrown, and primitive trail. Runners will cross meadows and streams, negotiate boulder fields, and may encounter mud, snowfields and wildlife such as moose, elk, deer, black bears and bighorn sheep. The 100 km and 60 km courses have substantial total elevation change and intermediate aid stations; one notable unsupported stretch between Ruby Jewel and Clear Lake is about 10 miles at high altitude.

Field size is capped (625 total entries split between distances). The race provides marked course flagging, full-service aid stations with varied food options and GF/vegan alternatives, drop-bag locations, and medical/communications coverage. Cell service is very limited; organizers advise carrying maps or GPX files and the required basic mountain gear listed in race rules.
