This course can be rough!

Make no mistake — many sections of the course are rough. To run the Wyoming Range 100 is to run on stretches of faint to nonexistent trail. Here are a few challenges you can expect on the ground:

  • Rough trail

  • Disappearing trail

  • Game trail

  • Side-hilling

  • Bushwhacking

  • Stream and river crossings

  • Mud

We created a color-coded trail conditions map

To help you prepare and navigate, we created a color-coded “course conditions” map that shows our (subjective) assessment of the condition of the entire course:

  • Green: Clearly visible trail

  • Yellow: Faint and/or overgrown trail

  • Red: No trail

The image below is a preview of our course conditions map. To give you an example of how the map works, you can see how the trail turns to red on the ridge leading up to Wyoming Peak. This means the trail is gone — you’ll be navigating by cairns and pin flags!

If running in the mountains without a clear trail gives you heartburn, then the Wyoming Range 100 is not for you. Like we said on our homepage, this is a graduate-level course.

How we mark the course

To help you battle our clandestine trail, we will thoroughly and consistently mark the course. You can learn about our course-marking methodology here.

Runners must carry the GPX track during the race

With nearly 100 miles of course markings, we can practically guarantee that some will disappear between when we hang them and when you run past them. In 2021, for example, we had about 0.25 miles removed by elk; we found half-chewed markings in a pile on the trail. The following year, we had about 0.10 miles disappear in a massive tree blowdown.

To adress the risk of “disappearing” course markings, we require all runners to carry the GPX track on a phone or GPS device. If you haven’t seen a course marking in about 0.30 miles, it’s time to check your position on the map.
