The 4th Annual Denver Gorilla Run takes place on Saturday, October 27, 2007 at 11am.

The Denver Gorilla Run is a charity fun run with a difference. Everyone who takes part wears a full gorilla costume - from fluffy head to furry toe - and helps raise funds for the Mountain Gorilla Conservation Fund, the international charity working to save the world's last remaining mountain gorillas and keeping Dian Fossey’s dream alive for the past 22 years.

Every participant in The Denver Gorilla Run will represent a group of real live gorillas in the wild. You will be assigned to either the Amahoro Group, Mubare Group, Sabinyo Group or the Rushegura Group - so with limited entries available you must register soon to secure your place.

Incidentally, the footer on their page (currently) says that there are approximately 723 Mountain Gorillas left alive today. This correlates with our current Mountain Gorilla fundraiser where we're trying to raise $720 for 720 Mountain Gorillas. As you can see from the Google Spreadsheet chart below we're off to a reasonable start, but we still have a long way to go to reach our target.
