On 22nd May 2009 I will set off from Land's End to ride over 850 miles to John O'Groats where I will arrive on 29th May. In so doing I will be fulfilling a promise made five years ago to Professor Roger Kirby when he removed my cancerous prostate and thereby gave me a new lease of life - namely that I would celebrate five years of that new life by undertaking a serious fundraising cycling challenge. Without Roger's skill and the research work and support of the charity of which he is the President I may not have been able to ride my bike at all today, let alone take on the infamous End to End challenge.
