I am not a runner. I walk at the same speed as a small child - probably due to the fact that I have short legs. Combined with the excuse that I haven't done much sport in the last year means it is going to be extremely difficult for me to make it round the 13 miles. Your generous donations will be a huge incentive for me on the day as I would like to raise as much money as possible for the NSPCC. However, if it comes down to it, I can always use the cash to get a taxi to the finish line.
