Coming to Denver (in August 2013) and San Francisco (in September 2013). But wait, not that kind of oyster. Oyster, The Race, started in Denver (think Rocky Mountain Oysters) and is “the ultimate urban hybrid adventure,” with teams of 3-6 on a mystery course around the city. The course ranges from 10 to 30 miles across 2 to 6 hours, meaning you need to be in shape but also be prepared for strategy, running, biking, kayaking, rock climbing and performing crazy stunts while solving clues around the city. And of course, it all ends with a big party for all.
