Umstead 100 Mile Endurance Run

The Umstead 100 Ultra is a 100 mile endurance run through the William B. Umstead State Park in Raleigh, NC. You have 30 hours to complete the race. There’s also a 50 mile option.The Umstead 100 Mile Endurance Run is designed to help new ultra runners make the leap from 50 mile runs to the more demanding 100 mile runs. It enables runners who have difficulty finishing 100 miles in 24 hours, or just finishing 100 miles at all, the opportunity to do so when severe topography, heat, and getting lost are removed as major obstacles. Many runners find the Umstead 100 an excellent foundation for the Massanutten 100, Western States 100, Leadville 100, and Wasatch 100 runs.
