Tampa Bay 100

Tampa Bay 100 is a 100-mile (about 160.9 km) trail ultramarathon held in Tampa, Florida, starting at 5:00 AM on November 14, 2026. The single event is the 100 Miler, and registration runs through UltraSignup. A pre-dawn start on a trail course of this length means most participants will run through the following night, so this is a race that demands respect for time on feet as much as for pace.

A 100-miler suits runners who already have several 50K or 50-mile finishes and want to step up, or experienced hundred-milers looking for a late-season race. Preparation usually spans five to six months, with back-to-back weekend long runs, regular night running with a headlamp, and a tested fueling plan for 24-plus hours of effort. Elevation gain is not listed for the course, so plan your training around sustained endurance and get comfortable running long stretches at a steady effort. Crew and pacer arrangements, drop bags, and foot care will matter as much as your training.
