Its three-loop course makes it one of the best races on the 70.3 circuit for spectators, who have multiple chances to cheer on their loved ones, all while enjoying two playgrounds, water slides, a kiddie pool, food vendors and the IRONMAN village. For athletes, IRONMAN 70.3 Florida is a popular early-season race, whether you’re a first-timer or a seasoned pro getting your legs ready for the year ahead. Expect a beach start, glassy freshwater lake swim, moderately hilly bike course past orange groves and through downtown, and an energetic three-loop run.
