Never Summer 100km & 60km

The Never Summer events are mountain trail ultras held largely inside State Forest State Park, running between the Never Summer Mountains near Rocky Mountain National Park and the Medicine Bow Mountains north of Cameron Pass. Two race distances are offered:

  • 100 km (approximately 65.7 miles) with about 14,500 ft of ascent and 14,500 ft of descent.
  • 60 km (approximately 39.2 miles) with about 8,100 ft of ascent and 8,100 ft of descent.

Courses sit at high elevation, with minimum and maximum elevations of 8,450 ft and 11,852 ft and an average elevation near 10,220 ft. Terrain includes alpine ridges and peaks, cross country sections, jeep and logging roads, rough and bomber trail, rocks, meadows and streams. Wildlife commonly seen on course includes moose, elk, deer, black bears and bighorn sheep.

Aid stations are fully stocked at multiple locations and there are planned drop bag points for each distance. The longest stretch without aid is 11.4 miles from the start to Michigan Ditch; a 10.0 mile high altitude section between Ruby Jewel and Clear Lake requires careful planning. Cell service is very limited on course. The race limits total entrants and publishes time allowances for each distance; crewing and pacing are permitted only at specified aid stations and access requires appropriate park passes.
