Uh. Lawks. I've only gone and signed myself up for it again.
I mean, do I have no memory!?
The thing is, I was at a most excellent stag-slash-hen do this weekend, which for us stags (I flatter myself) involved a very gentle game of cricket in the afternoon, before hooking up with the hens at a superb restaurant near Finsbury Park.
The key words being very and gentle game of cricket. The other crucial word being agony which I was definitely in the following morning.
Oh dear; time to do some exercise again.
So when the email from evil-Nike popped into my inbox on Monday - how could I resist.
