I am running 26.2 miles for the first time at the London Marathon on Sunday 23rd April.

I have been running for three or four years now, completing six or seven half marathons and feel I now need to make the step up. I was all set to run the Berlin Marathon last year, but for injury. This time round I am following a regimented training programme to make sure I get it right. 

I am writing about my journey at www.runningjaffacake.blogspot.co.uk.

Let's be honest, running a marathon isn't a challenge. It's what fit and healthy (albeit somewhat mental) people do as a hobby, or for a sense of personal achievement. Facing up and fighting against cancer is the challenge - they are the truly amazing people.

So let's run a marathon and raise as much money as possible to help cure cancer as soon as possible then. Yeh? Great.
