Sumo Run

The Sumo Run is an annual 5km charity fun run around Battersea Park, London, in Inflatable Sumo Suits.

Whether you're in training for the London 2012 Olympics or you just like dressing up at the weekends, Sumo Runs are your newest hybrid of serious exercise and self-expression. Except, of course, they're not very serious.

Sumo Runs raise money for UK-based education charity Gemin-i.
