The Blood Run, set for September 5, 2026, in Lennox, SD, offers an unparalleled endurance challenge on a charming 1.5-mile loop around The Good Earth Farm, an active organic vegetable farm. Runners can test their limits across a variety of timed events, including 3-hour, 6-hour, 12-hour, 24-hour, and 36-hour races, along with a 24-hour 4-person relay. This grassroots event, established in 2014 by "recovering ultra runners," is celebrated for its low-key, community-focused atmosphere, where participants often share the course with friendly miniature farm animals.

The course itself features mostly well-traveled dirt paths and some pasture sections, offering minimal elevation gain or loss, making it largely flat and accessible. Race day conditions typically see highs around 80F and lows around 57F, with a 12% chance of precipitation, so runners should be prepared for varying weather on the exposed prairie loop, which has very few trees. A single, fully stocked aid station is conveniently located on the 1.5-mile loop, ensuring runners have access to "real food," beverages, and even flush toilets on every pass. Flexible crew access, camping options at the farm, and a pre-race pizza dinner further enhance the runner and crew experience.

What truly sets The Blood Run apart is its unique blend of serious endurance running and quirky farm charm. The race's name itself is a humorous nod to a local monument, reflecting the organizers' lighthearted spirit. Runners striving for 100 miles in the 24 or 36-hour events can earn a coveted buckle, while everyone receives a unique marble for each completed lap, adding a distinctive touch to this memorable South Dakota ultra.
