Sufferfest on Section 4
Middleburg, United States • 9 Aug 2025
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 traverse a roughly 2.5-mile out-and-back single-track course 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, the race offers cold water, electrolytes, and pickle juice at the halfway point. Limited to 30 participants due to parking and trail constraints, it encourages carpooling and donations to support trail maintenance. The event is cupless, requiring runners to bring their own hydration and fueling supplies. Visit the organization's website for the most recent information.
