Dimbleby Cancer Care's Walk50 challenge

Over the last two years nearly 200 people have supported the Dimbleby Cancer Care charity by walking 50km through London. Starting at St Thomas' Hospital in Lambeth the walk's route takes in famous London landmarks including Trafalgar Square, Buckingham Palace, The Mall, the British Museum, the Tower of London, Canary Wharf, Greenwich and Lambeth and this year has extended the route out to Hammersmith and Fulham.

Walkers finish at Guy's Hospital, where the charity now has its new home at Guy's Cancer Centre.
