Summary: A course that’s often a buildup race for Bighorn and Hardrock runners, this tough race features runnable single track, long, extended climbs, and two times around 10,400 feet, not to mention technical descents and a remote section of cross country, grassy plains. In addition to the 50 mile race is a 50k and 15 mile option. New course in 2018 with a re-route section that is off-trail, steep, bushy, brutal and over fallen trees! See details here.

Lessons Learned from Race Reports

  • Cupless race
  • Mandatory gear list, including a bear bell through the Valles Caldera National Preserve
  • A few really technical sections, including steep ups and downs, with loose scree/sand/rock
  • Use the runnable single track when you get it because a lot of the course’s ups and downs are much less runnable
  • Many runners underestimate the course and the loooong climbs, at 8,000-10,000 feet, the climbs feel that much longer
  • Pay attention to course markings, as Elk tend to eat the flags and some markers get moved by hikers
  • Expect sections to take much longer than expected
  • Be ready for false summits on the two biggest climbs, as there are communication towers that look like the top, but they are not
  • Lots of exposure – remember hats, sunscreen, ice if it’s hot
  • Temperature swings with getting to that high of elevation along with dry air
  • Runners use this is a buildup race for Hardrock, so that tells you the difficulty level of the race
  • Off-trail sections in 2018 will make for slow, possibly frustrating miles
