Event details
The Tampa Bay 100 Mile Endurance Run is a point-to-point urban ultramarathon of 100 miles held on November 8, 2025 in the Tampa Bay area. Organized by Skunk Ape Events, this is the event's third year. The route begins in Ybor City and finishes near the 11th Ave Pier at Vinoy Park in St. Petersburg, passing through Tampa, Safety Harbor, Dunedin, Clearwater, Gulf Blvd, Gulfport, and downtown St. Pete. The course is mostly flat with some bridges, showing approximately 1,165 feet of elevation gain and about 1,218 feet of elevation loss. The event is presented as a self-guided endurance tour rather than a strictly competitive race; finish times are recorded and top finishers are recognized.
Course support, rules, and logistics
There are five staffed aid stations: Courtney Campbell, Cooper’s Bayou, Dunedin, Indian Rocks Beach, and Gulfport. Drop bags are accepted at Dunedin (between about 50 and 60 miles) and Gulfport (near 80 miles). Several supplies caches will be placed between aid stations; runners should also plan for stores and park fountains along the urban route. Cutoffs include Dunedin (reach by hour 19), Gulfport (reach by hour 29), and an overall cutoff of 36.5 hours. Mandatory items to carry include a cell phone, event direction sheet, at least one 20 oz water bottle or hydration pack, headlamp and extra batteries, reflective gear, blinking LED lights, and the CalTopo app with the course map. Crews must obey traffic and parking laws and may not pace from moving vehicles. Pacers may join after the Courtney Campbell Causeway; nighttime pacing allows up to two pacers and requires reflective gear and blinking lights.
