Running 10k is no mean feat especially when you’re dressed as a gorilla.

Last week gorilla runner Tomas Gisby ran the London 10,000 in his full gorilla suit and Gorilla Organization running vest, the same vest he wore for this year’s Virgin London Marathon.

This is Tomas’ second run this year for the Gorilla Organization and he soon be running his third on September 26th when he joins hundreds of other gorilla suited runners in this year’s 7km Great Gorilla Run.

If you think you could be a gorilla runner capable of running 7k, 10k or maybe even a half or full marathon in a gorilla suit contact sam@gorillas.org. We’ll be able to set you up with a fundraising page, provide all the information you need and give you a gorilla suit.
