<p>This Christmas Day I will run a half marathon. That's 13.1 miles.</p> <p>I understand it's an unusual time to do a half marathon. There isn't an organised race so I'm going to be doing it on my own. I'll start at Saltaire Train Station and follow the canal until I hit Leeds centre. That's 13.1 miles.&nbsp;</p> <p>I am assuming it will be a difficult thing to do. I don't know, I've never run a half marathon before. But I will on Christmas Day I promise. I'll electronically track it and publish the run on the internet.&nbsp;</p> <p>And I would like you to make a donation to Macmillan Cancer Support to mark the event.</p> <p>Earlier this year my friend and the mother of my wife, Megan Hind died. She was an immensely brilliant, courageous, defiant, beautiful woman. She is much missed. And she was much cared for by the Macmillan nurses. As I have been in my time too.</p> <p>In these difficult times it is hard to ask friends to donate to charity. So I thought that the combination of the physical challenge being carried out on Christmas Day might just be memorable and interesting enough to justify asking you to dig deep when things are so tight.</p> <p>The Macmillans are special people. Please help if you can.&nbsp;</p>
