Inspired by Dr Colin Clerkin, who has beaten cancer twice yet never stopped fundraising, I will be completing the 365challenge for Cancer Research UK (www.365challenge.co.uk). Over the course of the next 12 months, by 19/10/2011, on my way to the Boston marathon (April) and the London triathlon (July), I'll row the length of the Thames, 215 miles, run and cycle the distance from Lands End to John O'Groats, 1000 miles, and swim the width of the English Channel, 22 miles. Thank you for all your support, David.
