Orange County Adventure Race April 26, 2009

What: 10 miles (2-4 hours) of fun and excitement. You'll travel on foot, by bike, and by raft all over the Irvine Lake area passing through multiple mystery challenges and obstacles along the way. You'll laugh, you'll be challenged, and you'll get dirty doing it. And all finishers will get their dog tags!
