In the annals of obscure accomplishments, even this is out there.

More than 1,000 people in gorilla suits crammed streets and bike paths in LoDo Saturday morning, setting a Guiness World Record for the most people dressed as gorillas in one location. The 1,061 simulated simians were participating in the 6th annual Denver Gorilla Run, a 3.5-mile charity run/walk to help mountain gorilla conservation.

The event is organized by the Denver-based Mountain Gorilla Conservation Fund, which seeks to continue the work of slain gorilla researcher and conservationist Dian Fossey. The fund is in the midst of a drive to raise money for an expansion of a veterinary training facility in Uganda, in order to teach locals how to provide necessary veterinary care to mountain gorillas in their country.

Saturday’s run cost $99.95 for first-time participants to sign up — but came with a gorilla suit that runners got to keep. It followed a course through LoDo that began and ended at the Wynkoop Brewing Co.

The fastest runner finished in 22 minutes, according to race organizers.
