Comfortable temps, big temp swing

Mild 52°F temps at gun time mean comfortable early miles without overheating risk. Temps will climb significantly to 70°F by later miles, so expect fading conditions as the race progresses. Light winds shouldn't be a major factor for pacing.

Race Info

The 50K Ultra follows the marathon's double loop out of Sand Key Park, then adds a 2.5-mile out-and-back on the Pinellas Trail between miles 18.5 and 23.5. It carries the festival's most aid stations, 17 on course, spaced every 1.5 to 2.5 miles. Runners must average roughly a 12:06 mile through the mile-18.5 trail turnaround or are redirected to finish as a marathon finisher instead.
