I'm running 7km through the City in my gorilla suit partly to scare my children, and partly to raise money for the Gorilla Organization. I think this is a really worthwhile cause because not only are they saving the last few hundred mountain gorillas in the world, but they do so through education, poverty reduction, and conservation.

The last time I did it, four years ago, I was one of the fastest finishers to complete the whole run wearing my gorilla head. And this year I want to improve on my time. So think of me, sweating away under two inches of fur, and please give generously.

If I raise £500 my employer, Credit Suisse, will contribute another £500 - doubling your donation.

Donating through JustGiving is simple, fast and totally secure. Your details are safe with JustGiving – they’ll never sell them on or send unwanted emails. Once you donate, they’ll send your money directly to the charity and make sure Gift Aid is reclaimed on every eligible donation by a UK taxpayer. So it’s the most efficient way to donate - I raise more, whilst saving time and cutting costs for the charity.

So please dig deep and donate now.
