On a beach front, in sunny Marbella, enjoying a gentle jog up and down the front Kate and I experienced what was clearly a moment of madness when we decided to enter a serious running competition.

As a result, it's less than a month to go until we run 13.1 miles (or 21 kilometers!) all in the name of charity. 

Anyone who knows me well will know I'm no 'natural runner' and training has been tough, so give me an extra reason to keep pushing this last month, even if it's just £1.

In return we promise to post a disgusting, sweaty, red-faced pic of ourselves on Facebook as evidence!
