The route passes through Tampa, Safety Harbor, Dunedin, Clearwater, Gulf Blvd, Gulfport and St. Petersburg. The course is mostly flat with some bridges, about +1,165 ft total elevation gain and -1,218 ft total loss. There are five aid stations named Courtney Campbell, Cooper’s Bayou, Dunedin, Indian Rocks Beach, and Gulfport, plus several supplies caches between aid stations. Drop bags are allowed at Dunedin (between 50 and 60 miles) and Gulfport (near 80 miles). Hard cutoffs apply at Dunedin (reach by the 19th hour), Gulfport (reach by the 29th hour) and an overall cutoff of 36.5 hours.
Mandatory items include a cell phone, the provided direction sheet, at least one water bottle or 20 oz hydration, headlamp with spare batteries, reflective gear and blinking lights, and the CalTopo app. Pacers may join after the Courtney Campbell Causeway; pacers must follow crew rules and wear required reflective and blinking lights at night. Crew rules prohibit pacing from a moving vehicle and require legal parking and respectful behavior. Finishers of the 100 mile distance receive belt buckles and top finishers are recognized. The event is described as a self-guided endurance tour rather than a competitive race. Visit the organization's website for the most recent information.
