The 2009 Denver Gorilla Run, which set a new Guinness world record for the number of people in gorilla outfits, at 1061. There are only about 740 mountain gorillas left in the world (though this is significantly more than there were a few years ago). The run starts and ends outside our loft, and is sponsored by the Wynkoop Brewing Company (and others). See denvergorillarun.com.
