Race Details

Lessons Learned from Race Reports

  • Cupless race, at least for cold drinks
  • 1.5 miles into the race you’ll cross over a field of boulders running along the Pedernales River, followed by about 5-6 miles in a straight, gradually inclined line next to a wired fence that seemingly never ends.
  • Have a good headlamp!
  • The course is runnable for the most part, around two-thirds of the trail is mainly dirt and light rocks. The other third of the trail can be very technical (rocky) with slippery rocks, interspersed throughout the course.
  • Big difference between the first loop and second loop not only because of daylight for most of the first loop, but also because 2nd loop is quite isolated with runners being spread out.
  • The course was marked well for the most part, but there were some long stretches where you couldn’t spot a marker for what seemed like forever; keep your head about you as best you can in the dark and in the latter miles of the race in order to pay attention to where you are and not freak out if you don’t see a marker.


Total gain/loss: 2600/2600

Total climbs: 4×300 feet, but with lots of rollers within those climbs and in between the climbs. None of this race looks flat.

Longest climb: From miles 1.5-7.3, gain 300 feet with lots of false summits along the way, from miles 10.9-12.4, gain 300 feet with false summits. Since it’s a loop course, you’ll hit these same climbs at miles 19.7-25.6 and 29-30.6. Otherwise, lots of hills from 50-100 feet of gain.

Steepest climb: Countless climbs of ~100 feet in .2-.5 miles throughout
