The Stuffed Turkey Endurance Races 2026

The Stuffed Turkey Endurance Races are fall trail races held at Jester Park in Granger, Iowa. Participants can choose from 10-mile, 50K, 50-mile, and 100-mile distances. The course is almost entirely trail, featuring a mix of rolling hills and flatter sections. Each 10-mile loop includes 455 feet of elevation gain. The 50K, 50-mile, and 100-mile events are UTMB Index qualifiers, and the 10-mile offers a shorter option on the same park course. Aid stations are located at mile 5 and the 10-mile start/finish area, providing support twice per loop. The race is cupless, requiring participants to carry their own hydration vessels. Pacers are permitted for the 100-miler starting at mile 50, with each pacer completing a full 10-mile loop. Dogs and bike pacers are not allowed, with exceptions made for accessibility on a case-by-case basis. Participants receive shirts and finisher medals. The Jester Park Equestrian Center offers indoor space for crews. 100-mile starts are capped to manage support, and the event holds Trail Sisters Approved status.
