Around 1600 charity runners dressed as Santa Claus took part in the Disability Snowport UK fun run in Battersea Park.
The 6 kilometre run raises funds for the charity which helps people with disabilities, including cerebral palsy, Down's syndrome, visual impairment and autism, to take part in snow sports.
There was a strenuous warm-up before the event, as hundreds of Father Christmases limbered up in hats and traditional red garb.
Who won? The chap with the beard.
