I have been lucky enough to secure a place through my local running club for this year's London Marathon . Although I have run a few half marathons in my time (ok, all but one of them maybe 20 years ago!), this will be the furthest distance I have attempted by far.

As many marathon entrants do, I'm using the opportunity to raise money for a worthwhile charity. Details can be found here:

This is a charity that is very important to me, and if you're able to spare a few pounds, your contribution will be greatly appreciated.

Thank you for your support, and if you're anywhere near London on the morning of 26th of April (or lying in bed watching BBC 1 ), feel free to see me suffer on the day !
