Geoff Marshall
Marshall led a tube-based charity event in 2005 with Tube Relief. It was in response to the 7 July 2005 London bombings. Around 50 people took part, raising over £11,000 for charity. Marshall later did a series of Walk The Tube events to raise money for charities, by getting a group of people to visit every tube station but not as a record attempt. These events took place for three years following 2013.
