Sufferfest on Section 4

Sufferfest on Section 4 is a challenging 5-hour endurance event held in Middleburg, Florida, along the technical and hilly Section 4 of the Pioneer Trail. Participants run, walk, or hike as many out-and-back loops as possible on a roughly 2.5-mile single-track trail featuring switchbacks and scenic overlooks of Black Creek. The event embraces Florida’s heat and humidity, providing a tough heat-training experience.

While self-supported, aid stations with cold water, electrolytes, and pickle juice are available midway. Limited to 35-40 participants due to parking and trail constraints, the event encourages carpooling and donations to support trail maintenance. Awards include entries to future trail races.
