Thanks for visiting my JustGiving page! You may be thinking, why should I be sponsoring David for a 5k run when he's already got 6 marathons under his belt?

Well, the reason is simple - it's been literally years since my last marathon, and my days of raising £10k for charity in a year are behind me as I instead invest my efforts in bringing up the next generation of scientists.

I had hoped to have done a marathon in December, but alas I do not have a sufficient work life balance to both train for a marathon and teach effectively (yet!).

So, this may be a shorter run than my previous efforts, but my heart is still in raising money for charity when I can, and it would warm it greatly if you could maybe pop in a pound or two, not least because your donation will go to Comic Relief, a fantastic charity that helps those much less fortunate than ourselves.

Thank you!
