Two members of the Serpentine Swimming Club warm up with a glass of sherry after completing the Serpentine Swimming Club's annual Christmas morning 'Peter Pan Cup' race in Hyde Park, London, today (25/12/2013). The race, which takes place every Christmas Day on the Serpentine River, takes its name from from the novel by J.M.Barrie after the author presented the first Peter Pan Cup in 1904.
