The premier A-type race features the longest bike course in Japan, spanning 210 km (130.5 mi) and circling the entire island. To minimize traffic, driving is discouraged on event day, allowing runners and bikers to enjoy the support of spectators and 5,000 volunteer staff.

At Hey Japan!, we strive to keep the events listed on our website as current as possible. However, event organizers may cancel events, alter schedules, or modify admission requirements without prior notice. Check official websites before attending any event.
