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.

How to register
Registration opens each September for the following spring. The first 265 entries are taken online, first come, first served, and a Second Chance Lottery a few days later adds 50 more; the 100 and the 50-mile option share one registration. For 2027 the first round opened at 8 p.m. on September 16, 2026 and the lottery took applications from September 19 to 26, and the race says all registration has concluded.
