Trails 4 Tails Ultra Run

Trails 4 Tails Ultra Run takes place in Hanover, Pennsylvania, on September 19, 2026. The event offers three trail formats on the same day: a 40-mile ultra starting at 7:00 a.m., a 40-mile relay that sets off at 7:45 a.m. so teams can split the distance, and a 25K (about 15.5 miles) with a later 8:30 a.m. start. All three are run on trails, so expect a course that rewards steady effort and good footing rather than raw road speed.

If you have finished a 50K and want to see how your body handles a full day out, the 40-mile solo is a natural next step, while the relay lets a group of friends share the work and the miles. The 25K works as a long trail race for road runners curious about dirt. For the 40, plan on roughly 16 weeks of preparation with back-to-back long runs on weekends, hiking practice on climbs, and a fueling plan you have tested on your longest training days.
