RUN&MOSH リレーマラソン in 彩湖 2026

The RUN&MOSH Relay Marathon at Sai Lake is an annual MOBSTYLES festival run held at Sai Lake in Toda City, Saitama Prefecture. The primary event is a two-hour relay marathon designed for teams of two to four people. Teammates share the running distance, rather than each completing a full marathon. A solo option is also available, covering approximately 9.4 km, which is two laps around Sai Lake. This event, which began in 2022, is intended for those seeking a social race day alongside a challenging effort. The course consists of laps around Sai Lake, offering a straightforward format for both relay teams and individual participants. Beginners are encouraged to join, and the relay structure allows friends to compete together without requiring equal running contributions from each member. MOBSTYLES provides participants with a limited-edition event T-shirt, and prizes will be awarded. The event feels more like a yearly gathering for runners, friends, and MOBSTYLES enthusiasts than a traditional formal road race.
