IRONMAN Japan South Hokkaido
About the event
IRONMAN South Hokkaido offers triathletes an unforgettable challenge across the stunning landscapes of southern Japan on September 12, 2027. The swim segment plunges athletes into Hakodate Bay's crisp waters for a grueling yet invigorating 3.8 km course. Participants then transition to the bike leg and take off along the scenic Hakodate-Esashi Expressway, covering an arduous 180 km route that tests endurance and mental fortitude against varying road conditions. The event concludes with a flat and fast 42.2 km run through Kikonai's serene countryside, where runners can soak in panoramic views of rolling hills and lush farmland while pushing for their personal bests.
