Sufferfest on Section 4

Sufferfest on Section 4 takes place on August 8, 2026 in Middleburg, FL. The event is a five hour running event held on Section 4 of the Pioneer Trail and uses an out and back format along the same trail section.

Section 4 is about 2.5 miles one way. The route is mainly single track, technical and hilly, with switchbacks and overlooks of Black Creek and scenic vistas. Hot August conditions and high humidity can affect conditions on the trail.

The field is limited to about 40 to 45 participants because the course is single track and parking at the Phillips Branch parking area is limited. The event is cupless; participants are expected to carry their own hydration and fueling. Organizers will provide at least one igloo with cold water, Skratch electrolytes and some pickle juice at the halfway point (about 2.5 miles), though that station may not be continuously staffed.

The event is free to enter and organizers invite voluntary donations on the event day; any collected funds will be donated to the Friends of Florida State Forest. There is no formal timing, but organizers will track loop counts. The participant with the most out and back loops receives a complimentary entry into either the SOS trail race in September or the Premier Trail Race Festivus 100 in December up to a 50 mile entry, and a separate random entry prize will also be awarded.
