For the fourth year in a row, I am running 26.2 miles through the streets of London. And once again, I am raising money for Hearing Dogs for Deaf People, my favourite charity.

For those of you who don't know, Hearing Dogs train dogs to help deaf people live normal lives. This in itself is fantastic, but the dogs they train are the ones abandoned and left in shelters who may themselves have only had little chance in life. In one move they help people and animals in a way that is truly amazing.

This year, I am trying something different. I need to raise £1600.00 for my charity. As an advocate of social media, over the years I have built up a lot of friends and contacts. By my reckoning, I should have at least 800 people in my sphere.

So what I am asking is that you donate £2.00 to my cause. Things are tough for all of us, so if we work together we can do great things.

Of course, if you would like to donate more, then that would be wonderful, but I am setting myself 6 weeks to collect at least £2 from 800 people or more.

It would be wonderful if you could help, and pass this link on to anyone you think would like to get involved.
