Prepare for an unparalleled test of endurance at the More Miles Last One Standing Challenge, set to unfold on May 30, 2026, in scenic Knoxville, MD. This isn't just a race; it's a vibrant "backyard ultra" experience, offering both an official 4.167-mile loop and a 1-mile "backyard for mortals" option. The main 4.167-mile event serves as a qualifier for the Backyard Ultra world championship, challenging participants to complete a loop every hour, on the hour, until only one runner remains. For those seeking a different kind of challenge, the 1-mile event provides a more accessible entry point, running for 24 hours with a tie-breaker protocol that adds an extra mile each subsequent hour until a single champion emerges.

The race takes place at the Manidokan Camp and Retreat Center, where the 4.167-mile course is a 2.084-mile out-and-back journey. Runners will navigate non-technical terrain, including dirt trails with minimal rocks and roots, packed gravel, and grassy sections, featuring 533 feet of ascent and descent per loop. The 1-mile course offers a gentler experience, consisting of two half-mile loops entirely on mowed grass, with directions alternating hourly. Participants can expect typical race day conditions with highs around 78°F and lows around 57°F, and a 16% chance of precipitation. The unique camaraderie of a backyard ultra creates an engaging atmosphere, where runners often push each other further than imagined.

The seventh annual More Miles Last One Standing Challenge prides itself on its social, "backyard BBQ" vibe, while still delivering a rigorous ultra experience. On-site camping is available at the start/finish village, allowing runners to set up their personal aid stations and recharge between laps. A small aid station offers water, Tailwind, and light snacks, with campfire fare and pancakes also available at certain times. This cupless event encourages runners to bring their own hydration vessels and plan for their larger fueling needs as they strive to be the last one standing. The 2026 edition even boasts prize money for both the ultimate champion and "the assist," recognizing the teamwork inherent in this unique format.
