And now, the end is near... Is that a bit melodramatic? Yeah, probably. It's just that I'm sitting here about to grab my shorts and trainers, jump on a (no doubt) sweltering tube and head to Harley Street for what should be the first of many such visits.
Relax, it's nothing terminal. Just the chance to do some exercise under expert supervision with a view to something really - and I mean REALLY - stupid. Every year, in a donkey farm near Wolverhampton, a cross country race takes place. In the depths of winter. With an assault course.
Some people set themselves the target of completing a marathon. I've been challenged to do the Tough Guy.
For most people, this would be a challenge. For a man who makes a living from eating, drinking, watching films and playing video games, it's possibly suicide. Still, only one way to find out, right?
