The Jug End Loop Ultra is scheduled for August 22, 2026. It features two events: a 4.2-mile run and a 6-hour ultramarathon. The 4.2-mile race starts at 8:00 AM. The 6-hour event permits runners to complete as many 4.2-mile laps as possible before the cutoff. In the final hour of the 6-hour event, a 0.75-mile "mini jug" loop will be available. No incomplete 4.2-mile laps count after the 6-hour mark.
