Prepare for a unique endurance challenge at the Cotter Bridge Ultra, set against the scenic backdrop of Big Springs Park in Cotter, AR, on June 13, 2026. This distinctive event, formerly known as the Arkansas Backyard Ultra Championship, offers runners a choice of 1, 3, 6, or 12-hour timed races. Participants will tackle a 2.08-mile out-and-back loop along a mostly flat, soft gravel course, 8-10 feet wide, that gracefully traces the White River. This well-maintained path, offering ample shade and minimal elevation change, ensures a straightforward run where getting lost is impossible. The true test lies in the format: each 4.1667-mile lap must be completed within 59 minutes and 59 seconds, with "hot laps" on hours 1, 3, 6, and 12 adding a competitive edge for the fastest finishers.

Typical race day conditions in mid-June include highs around 86°F and lows near 66°F, with a 14% chance of precipitation, creating a warm, humid atmosphere. However, Big Springs Park boasts a delightfully cold swimming hole for post-lap relief. While runners are expected to be largely self-sufficient, water and basic nutrition are available at the start/finish pavilion, and "The One More Yard Cafe" provides meals for all participants at the 6 and 12-hour marks. Known for its family-friendly vibe, the venue also offers fishing, swimming, a rope swing, and a playground, making it an ideal race for both seasoned ultrarunners and those looking to experience the unique format of a timed endurance event.
