On Saturday 27 September, the streets of London will be invaded by gorilla-suited runners, going ape for a day to help to save the world’s last 720 mountain gorillas.

Playing on the idea of gorillas taking over London, our friends at Bikini Films have made short movie featuring ranting Londoners and gorillas driving buses, to help spread the word to those who don’t already know about the run.

Click here to check it out.

Please help us spread the word by posting the video on your Facebook page or email the link to all your pals.

Fear not though, there’ll be no grumpy, ranting gorilla haters on run day so come along and run or cheer the great gorillas on - Go Gorillas!
