Looking to launch your summer triathlon season? Head to Palo, IA for this multi-format event featuring Sprint, Olympic, Aquabike, and open water swim options perfect for everyone from seasoned competitors to newcomers. The popular Sprint distance (.5K swim, 25K bike, 5K run) tends to sell out quickly, while the Olympic distance (.1.5K swim, 40K bike, 10K run) offers a bigger challenge—both welcome relay teams with prizes for top finishers, and the race uses chip timing with a time-trial swim start where athletes launch every 3 seconds by age group wave beginning at 7:30am.
