There are 270 tube stations in London and Sam Cullen's mission is to visit a pub near every one. He was inspired to do the challenge after watching a documentary celebrating 150 years of the tube and began at Paddington Station where the first underground train departed in 1863. He began in 2013 and he’s due to finish this March. His final pub of this challenge will be on 5 March, The Defector's Weld, in Wood Lane, the last station to open. He’s still enthusiastic about the endeavour — perhaps because he sees the light at the end of the (tube) tunnel.
