2024 SADO Island Long Distance International Triathlon （9.7）

This competition features several courses set amid the landscape of the entire island of Sado, and attracts 2,000 participants from both inside and outside of Japan. The A-type (long distance) race boasts the longest bike course (210 km/130.5 mi) in Japan, going around almost the entire island. Driving is discouraged on the day of this event so that traffic is minimal, freeing up the roads for runners and bikers, and enveloping them in the supportive cheers of spectators and 5,000 local volunteer staff.
