I'm doing the Great North Run in September - a half marathon. That's 20km or over 13 miles. Right now, I don't think I've ever walked that far, never mind run it.

I'm doing it to raise funds for Home-Start International, the charity I work for. Home-Start does amazing work helping families with young children and I'm hoping to raise £1,000. Actually, £100 would go a long way - this is a small charity with a big reach, helping local Home-Start projects in 20 countries around the world.

My sister Leah is running with me (actually, she'll be far in the distance ahead of me) and while we're not exactly looking forward to it, we're having some fun doing the training together.

So give if you can and if you can't, wish us well!
