Garth Ravenhill, was diagnosed with Parkinson's 7 years ago. As Garth has not taken part in any race further than 10k before he is unsure how his body is going to cope but is determined to finish the London Marathon.

CPT supporter Garth said, "I want to show people that you can achieve great goals and mine is the London Marathon. I've never really run before and to do this would be a personal victory against this disease. Race day will be so exciting, mixing with fellow runners, looking at all the other charities that are being represented, as well as the professional runners. I can't wait... My goal is to finish in under six hours but it will depend how my disease acts on the day. But no matter what, I will finish. I promise."

We are immensely proud of our 'Team CPT' running the London Marathon and raising funds for research and awareness of Parkinsons.
