Denver Gorilla Run
The 6th Annual Denver Gorilla Run is a great way to run/walk 3.5 miles downtown, get a free lunch, break a world record, give to charity, oh--and do it all in a gorilla suit that's yours to keep. It's also at 11:00am, leaving plenty of time for Halloween festivities later in the day.
