Embark on an unforgettable ultra-running journey at the Umstead 100 Mile Endurance Run, set for March 28, 2026, in the scenic William B. Umstead State Park in Raleigh, NC. This revered event, also offering a challenging 50-mile option, is renowned as an ideal proving ground for aspiring 100-mile finishers and a strategic training race for seasoned ultrarunners. Runners will navigate eight (or four for the 50M) 12.5-mile loops along wide, well-maintained multi-use trails, primarily composed of hard-packed gravel, offering excellent footing without technical single-track sections. The course features rolling hills, accumulating approximately 7,250 to 8,000 feet of elevation gain over the 100 miles, making it entirely runnable with nicely spaced climbs that become a true test of grit in later laps. Typical race day conditions in late March include comfortable highs around 66°F and lows near 44°F, with a minimal 16% chance of precipitation.

The Umstead 100 distinguishes itself with its exceptional runner support and vibrant community atmosphere. The start and finish lines are conveniently located at Camp Lapihio Headquarters, which also serves as a fully stocked aid station with hot and cold food, beverages, and first-aid supplies. Additionally, a second full-service aid station, "The Ptomaine Tavern," is positioned around mile 7.15 of each loop, ensuring runners are never more than 3.8 miles from hydration and sustenance. Crew access is seamless at the start/finish, with dedicated canopy areas creating a lively corridor of support, providing a crucial mental boost with every lap. Pacers are permitted after 50 miles, further enhancing the supportive environment.

Founded in 1996, the Umstead 100 has a rich history of fostering the growth of ultra-running, particularly for those looking to conquer their first 100-mile race, by mitigating common challenges such as extreme topography and the risk of getting lost. The clearly marked course, aided by glow sticks at night, ensures straightforward navigation throughout the 30-hour time limit. Beyond the race, the event cultivates a strong sense of camaraderie, highlighted by traditions like the Blake Norwood Memorial Awards for active-duty service members and a communal pre-race spaghetti dinner. Participants consistently praise the dedicated race directors, the enthusiastic volunteers, and the overall well-organized experience, making the Umstead 100 a highly recommended endurance challenge.
