<p>I would have liked to do the half-marathon but my Mum says I can't because I'm only 9 and I have to be a grown-up to run that far!</p> <p>I have decided to do this run in aid of the St Helier and Surrey Kidney Patient Association because my Nanny's partner has renal failure and he works with this charity to help other people with their dialysis and treatment.</p> <p>&nbsp;</p> <p>So please dig deep and donate now.</p>
