A Banksy mural will decorate the brass medal awarded to every runner in a half marathon.

The world-famous graffiti artist painted a scene of a little girl playing with sandcastles marked “Tesco” on a portion of the promenade wall opposite St Leonards Parish Church.

Eric Hardwick, race director of the Hastings half marathon, says the image will adorn the medal awarded to the thousands of finishers on March 20.
