I have never been a runner. But then, back in 2014 when we started Le Cure, I'd never been a cyclist, either: perhaps that's the point?
On January 25th of this year, I ran 15km for the first time ever; on February 21st, I ran my first ever half marathon; and on Sunday, May 3rd, I'll - hopefully - run my first ever marathon. And it will hurt like hell.
So why am I doing this? Well, the same reason I do most of the stupid physical stuff I do nowadays - Le Cure. This little charity bike ride we set up back in 2014, that's grown into one of the best things any of us have ever done, with hundreds of people taking to their bikes and heading out to the Alps every summer to ride really far, and climb really high, to raise £3.8m to fund research into curing cancer at the Royal Marsden.
And now, yes, we're running too. Not because we like running (although, confession time, I like it a lot more than I did last November), but because in many ways, me running a marathon is even more preposterous than me riding a bike up some mountains, and when it comes to raising money, the more preposterous (and painful) the better.
One day, no doubt, I'll be asking for your support and your sponsorship for something I secretly really want to do: but not today.
Sponsor me today, because this is really going to hurt, and because cancer's a horrible, horrible thing, and because the Le Cure fellowships at the Marsden are working to cure it.
