Aid Stations and Support
There are five dedicated aid stations: Courtney Campbell, Cooper’s Bayou, Dunedin, Indian Rocks Beach, and Gulfport. They provide soda, pickles, candy, chips, cookies, produce, and electrolyte powder. Additional "supplies caches" with water and snacks are placed between aid stations. Runners are advised to carry their own food or purchase it from stores, delis, or restaurants along the route. Crews are highly recommended but not mandatory.
Rules and Requirements
The overall cutoff time is 36.5 hours, with specific cutoffs at the Dunedin (19 hours) and Gulfport (29 miles) aid stations. All runners must carry mandatory gear: a cell phone, direction sheet, water bottle or hydration pack (minimum 20 oz), headlamp with extra batteries, reflective gear, and blinking LED lights for night running. The free CalTopo app is required for navigation.
Pacers are allowed after the Courtney Campbell Causeway aid station. Runners aged 60 or over may have a pacer at any time. Daytime pacing is limited to one pacer at a time; nighttime allows for two pacers.
