At the ripe old age of 46 I've decided to put my body to the test again and enter a white-collar boxing event. Stupid? Yes. Exciting? Yes. Bricking it? Yep.

The other guys will inevitably be a lot, lot younger, fitter, faster, stronger but, hmmm, but...well I know what I'm letting myself in for  having done this twice before!

2007: win

2009: draw (1 week before my wedding!)

It's been 14 years since I put on any boxing gloves so here goes nothing! I'm going to give up booze for the duration and absolutely throw myself into the training.

And it's all for a good cause: Lives not Knives. There's a worrying amount of violence in London and this is a charity that seeks to make a meaningful difference.

I hope you can support me and the cause. OK so I might get bruised and battered for a few weeks, but knife crime is another level…
