Nearly twenty year ago,, with the help of my friend Nick Baily, I pushed my dad's wheelchair in the Great North Run for the Calvert Trust (pictured), Dad was one of their trustees.

Now, like Dad had,  I have MS, am a Trustee of the Calvert Trust and feel like doing something similar. I  persuaded my friend Jason - persuaded sounds strong, I asked him, he said yes - to help me do the London Marathon.

The Calvert Trust says, it's not about what you can't do, it's what you can do. We think they are right. Please give generously!
