It's always been a huge goal of mine to run the London Marathon, something I wasn't sure I would get round to. But since starting running last year and running The London 10k, I had to take the opportunity to step up for the big one. I'm delighted to be doing it for such a great charity with Guide Dogs, so please do give what you can to support them in return for my painful efforts!

Almost two million people in the UK are living with sight loss that has a significant impact on their daily lives. Of those, around 180,000 rarely leave their homes alone and lead lonely, isolated lives. Guide Dogs works for a world where people with sight loss are never left out of life, for a world where being blind or partially sighted is not what defines you. A world with enough support to make the challenges of sight loss no barrier to fulfilling hopes and dreams.
