Simon brings new meaning to the word 'giving'. He joined the Anthony Nolan register in 2008, which the charity uses to match blood cancer patients in need of a potentially lifesaving transplant to remarkable people willing to donate their blood stem cells. For these patients, a stem cell transplant is usually their last chance of life. Simon came up as a match for a patient in October 2010, and donated his stem cells in January 2011. After his donation, Simon was so inspired by the charity's work that he ran the London Marathon on their behalf earlier this year, despite not being a runner and having only two months to train for the gruelling event. He says, "The marathon was the hardest day of my life, but I would have made it to the finish even if it meant crawling the whole way." In doing so, he raised over £1000 for the charity, which urgently needs funds in order to keep growing its register.
