Cycle Ball Oichi Special DAY (First 50 Entrants Only) (【先着50名限定】サイクルボール おおいちスペシャルDAY)

Izu Oshima, billed as the closest cyclist's paradise island to central Tokyo, hosts a special group day of Cycle Ball, a ride that takes in the volcanic geopark landscape. Riders choose between a main course of roughly 55 to 65 km with around 1,400 m of climbing and a short course of about 40 km with about 800 m of climbing, declared on the day. Both start and finish at Motomachi Port or Okada Port, and the start point shifts to match the day's ferry arrivals and departures.
The format is free ride, so everyone sets their own pace, and insurance is included. Because the event brings several riders together on the same course, questions about using the app can be answered on the spot. Finishers earn a completion card and Cycle Ball currency in the app on their first stage completion, and every participant receives a Cycle Ball T-shirt to mark the opening of the second half of the season from autumn.
