LATR Backyard Ultra 2026

The LATR Backyard Ultra is a solo backyard ultra held in Wausau, Wisconsin. Runners begin a 4.167-mile loop at 9 a.m. on Friday, with subsequent loops starting every hour on the hour. This event follows the Big Backyard Ultra format, requiring participants to complete each loop within the allotted time to start the next. The race concludes only when a single runner remains. The loop primarily consists of trails within Sylvan Park. The challenge stems from the repetitive nature of completing the same park circuit as fatigue accumulates, rather than a single strenuous effort. The event is associated with Lazarus Lake, the originator of the Barkley Marathons and the Big Backyard Ultra format. Historical results indicate this race has a track record extending beyond a single local occurrence.
