The Never Summer 100km will take place within the boundaries of State Forest State Park and run between the Never Summer Mountains on the northern border of Rocky Mountain National Park (RMNP) and the Medicine Bow Mountains to the north of Cameron Pass. This is a mountain race in the truest sense of the term, with extended periods of high alpine ridge running, two alpine peaks, and five alpine lakes visited along the way. The race covers a huge variety of terrain, from cross country, to jeep and logging roads, to bomber alpine trail, and pretty much everything in between. There are some sections of the course that have seen very little foot traffic in recent years and are rough and overgrown as a consequence; this only adds to the ‘charm’ of the race.
