About this race

A challenging ultra-distance mountain race featuring extended high alpine ridge running, two alpine peaks, and five alpine lakes. Runners will see the northern Never Summer Mountains, RMNP peaks, and North Park vistas. The course includes cross country, jeep roads, logging roads, and alpine trail. Expect mud, rocks, and potential snowfields. Some sections are rough and overgrown. The course runs between 10,000ft and 12,000ft and demands adequate training and mental fortitude.
