Sufferfest on Section 4
This is a five-hour out-and-back event on Section 4 of the Pioneer Trail near Middleburg, FL. Participants traverse a mainly single-track, technical and hilly section with switchbacks and overlooks of Black Creek. The organizer describes the format as a "Fat A$$" event in which each person repeats the section as many times as they can within the allotted five hours.
Course details include an approximate one-way distance of 2.5 miles, with out-and-back laps along the same trail. Terrain is technical with hills and scenic vistas. Heat and humidity in early August are noted factors for this location.
Support is limited and the event is cupless. Participants are expected to provide their own hydration vessel and fueling supplies. Organizers will provide at least one igloo with water, an igloo with Skratch electrolytes, and some pickle juice at the halfway point; these stations may or may not be staffed.
Field size is limited to about 40 to 45 participants to accommodate single-track running and restricted parking at the Phillips Branch or "4 way" parking area. The event operates without formal timing but includes a method to tally loops; the top loop performer receives a complimentary entry to a later race, and a random entry giveaway will also be offered. Proceeds for voluntary donations are intended for trail maintenance through the Friends of Florida State Forest. Visit the organization's website for the most recent information.
