In Billings, Montana today, Dean Karnazes ran 26.2 miles in less than 4 hours. It was an amazing feat considering the fact that he has now run 12 marathons in 12 days in 12 states in his remarkable Endurance 50 quest. It was the fifth time he dipped beneath the 4 hour threshold. My goal is to do that just once in my life! He's done it five times in less than two weeks! Next stop: Boise, Idaho.
