Pineapple Dance Studios star Louie Spence has launched a charity challenge with Sport Relief and its official partner Sainsbury's to break the world record for the longest 'sock slide'.

Taking place at eight supermarkets around the UK until March 2, participants must purchase a pair of Sport Relief socks priced at £2.50, with £1.25 going directly to the charity. The winning entrant from each location will receive a £100 gift card to spend in store.
