Come the 15th of April this year I will be running the Brighton marathon, after signing up during a mild bout of self rightiousness last summer. I've started training and am enjoying it so far (it is very early days). The goal is to run it in sub four hours. I'm keeping a blog to track my training, which will be updated once or twice a week http://marcusruns.tumblr.com/. Please read, comment, laugh, cry or do whatever else it amuses you to do.

As some of you will know, I've spent quite a bit of time caring for or representing disabled people, and see this as a fantastic opportunity to raise some money for Scope. Scope do amazing work, primarly with people with cerebral palsy, but also representing disabled people as a whole.

Please do give generously - some possible donations are:

£1.00 – Number of times Paula Radcliffe had to wee during 2005 London marathon (hopefully one more than me)

£5.94 – One penny/mile run in training (approx)

£9.16 – My target min/mile pace (I promise I won’t ask for more if I slow down)

£26.20 – One pound/mile

£42.16 – One pound/kilometre – for the metric lovers amongst you

£1,000,000 – Just in case any of you are secret lottery winners/Roman Abramovich.

Do come down to Brighton if you want to support/laugh/confirm that I've finished with your own eyes.

Marcus.
