About
The Umstead 100 Mile Endurance Run is designed specifically to help newer ultrarunners take on the demanding 100-mile distance for the first time. It minimizes many of the obstacles that typically derail first attempts, such as rough terrain, extreme heat, and tricky navigation, which significantly improves participants' odds of reaching the finish. The race also doubles as an excellent tune-up for more demanding mountain ultramarathons down the road, welcoming runners of every experience level and a wide range of personal goals.
