Never Summer 100k & 60k

The Never Summer races run almost entirely inside State Forest State Park between the Never Summer Mountains near Rocky Mountain National Park and the Medicine Bow Mountains north of Cameron Pass. Two distance options are offered and a combined option is available:

  • 100 km, 65.7 miles, about 14,500 ft total ascent
  • 60 km, 39.2 miles, about 8,100 ft total ascent
  • Dirty Double, both distances

Courses lie mostly above timberline with extended alpine ridge running, alpine peaks and alpine lakes on the route. Terrain includes primitive singletrack, rough trail, cross country sections, jeep and logging roads, meadows, streams, boulder fields and mud. Typical elevations range from about 8,450 ft to 11,852 ft and the average elevation is listed near 10,220 ft.

Aid stations are staffed and stocked, with a mix of full service and limited stations, drop bag locations and published intermediate cut offs. Crewing and pacers are permitted only at designated aid stations and park entrance passes are required to access aid locations. Cell service is very limited so maps and GPX files are provided and recommended for navigation. Wildlife on course may include moose, elk, deer, black bears and bighorn sheep. Registration is capped with specific entry limits per distance and time allowances are specified for each race distance. Visit the organization's website for the most recent information.
