Sumo wrestlers are not known for their distance running prowess, but hundreds will take to Battersea Park next month anyway.
These inflatable runners will wobble around a 5km course to raise money for the Link Community Development International (LCDI) charity.
A previous Sumo Run set the Guinness World Record for the largest gathering of people wearing sumo suits.
LCDI works to improve education for children living in sub-Saharan Africa.
