The full Sado Circuit, the route used in the Sado International Triathlon and the Sado Long Ride 210, is one of Japan’s most popular cycling routes. The loop can be ridden all at once or gently over the course of several days with detours along the way. Some portions of the route have no convenience stores or supermarkets at all, so do be prepared with your own supplies. Check map for the location of toilets, bike shops and cycle stations.
