In 2003, just a year after retiring from professional football, Geoff Thomas, was diagnosed with chronic myeloid leukaemia (a form of blood cancer) and was given just three months to live. However, after receiving a stem cell transplant from his sister Kay and undergoing treatment from Professor Charlie Craddock CBE, co-founder of Cure Leukaemia, Geoff entered remission in January 2005. This life-saving treatment has motivated him to give back, dedicating himself to raising awareness and funds for blood cancer patients across the globe.
In May 2025, Geoff Thomas announce he will ride the Tour de France, 20 years since he first completed the iconic 21 stages. He will be raising vital funds for Cure Leukaemia, a cause close to his heart having overcome chronic myeloid leukaemia himself twenty years ago.
