This Run Is Very Hard

The Zane Grey Highline Trail 50 Mile run is one of (if not the most) difficult 50 mile races in the country. It is an advanced degree run for experienced ultrarunners. This means if you have never participated in an ultra distance run before (sorry…triathlons don’t count) then do one of the many other ultra runs around the country before running the Zane Grey 50. There are sections of this course where you are out on your own for very extended periods of time without aid. You have to have proven that you can be self-sufficient. Race management would like to avoid having to send out search and rescue to retrieve runners on the course. We’ve had to do this several times in the past (we’re not kidding).

Trail Work Requirements

Zane Grey 50 Endurance Run does not at this time have mandatory trail work requirements. However, we strongly encourage all participants to spend volunteer time on the trails, especially the Highline Trail #31. Not only does volunteering to maintain the Highline Trail #31 help keep it safer and more enjoyable to run it’s also an excellent way to learn more about the area and the trail before race day. Trail work days are scheduled throughout March and April each year prior to the run and you can add your name to the notification list here.
