Cycle Ball Ooichi Special Day (Limited to First 50 Participants) (【先着50名限定】サイクルボール おおいちスペシャルDAY)

Experience the cycling paradise of Oshima Island, just off Tokyo's coast. On December 19, 2026, cyclists can choose between two courses tailored to their skill level: the main course at about 55-65km with an elevation gain of around 1,400 meters, and a shorter option covering approximately 40km with roughly 800m in altitude. Both routes wind through Oshima's stunning volcanic landscape within Izu Ōshima Geopark.
The event offers the perfect opportunity to explore this unique terrain at your own pace, thanks to its free-ride format supported by an easy-to-use app that helps participants navigate and connect with fellow cyclists sharing the same course on the day. Safety is ensured through insurance coverage provided for all riders.
After completing the challenging yet rewarding loop around Oshima Island, finishers will receive a digital "finish card" and cycle currency in their app accounts (limited to first-time stage completion). To celebrate the start of the autumn season's second half, every participant also gets a commemorative T-shirt at no extra cost.
Whether you're looking for an invigorating day out or planning a memorable island getaway, this event provides both scenic beauty and camaraderie among fellow cyclists.
Join us on December 19, 2026, to discover the captivating allure of Oshima Island's cycling trails!
