About the Event

This monthly race, backed by Kawasaki city, is run from Seta in Takatsu ward with the idea of a marathon version of radio calisthenics, an event any runner can join casually. The organizers put particular stress on emergency care: the medical team is led by volunteer leaders who serve at major marathons, and the setup is modeled on big races so that an AED can be reached within 1.25 km. Junior and senior high school athletic clubs, mainly from around Kawasaki, are invited free of charge. Distances are 1 km (a parent may accompany a child), 3 km, 5 km, 10 km, the half marathon and 30 km. The committee says it cannot stage a large event, but wants runners to finish smiling and without accident.
