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.
The run (100 miles or 50 miles) must be completed in 30 hours.
There is a cutoff time of 26 hours (8 am, Sunday) at the 87.5-mile point (the start of the last lap). Any runner who continues after that time/point is not guaranteed support.
Crews are welcome, but are not crucial for this race. There will be a voluntary crew briefing at Race Headquarters Saturday morning after the runners start (see the Race Schedule). Crew members are allowed at the start/finish at any time, but please respect the effort of all the runners and stay out of the way.
Crew members are allowed on the course to pace their runner either after 6 pm, Saturday, or at the start of lap 5, if started earlier than 6 pm, or as expressly permitted by the Race Director or Aid Station Captain.
Crew members may not use bicycles to accompany or crew runners on the course at any time. Doing so will result in a runner disqualification. There will be no crew or runner parking on the park access roads leading to or at Race Headquarters.
We like to think of the Umstead as a one-big-happy-family type event. Race crews are welcome to assist with the operation of the aid stations. We appreciate any assistance, just come on up and offer to help. Our only requirements are a smiling face and patience with our runners.
