About

The Umstead 100 runs eight 12.5-mile loops on the wide crushed-gravel bridle trails of William B. Umstead State Park, on the edge of Raleigh. The hills roll rather than climb, 8,000 feet in all, and the surface is forgiving, which makes it one of the more common places to run a first hundred or a fast one. A 50-mile shares the course, and the race has run each spring since 1995.

The race starts at 6:00 a.m. and holds a 30-hour cutoff. Entry is first come, first served and fills fast, opening in September for the following spring, and a finish counts as a Western States 100 qualifier.
