Last February, 59-year-old Ned Overend, aka “The Lung,” aka “Deadly Nedly,” won the first National Fatbike Championships, held in Ogden, Utah. Fat Bike Nats isn’t exactly the Tour de France, but it’s no charity ride, either. Overend had to compete against a field of much younger pros, including former national mountain bike champion Travis Brown, 46, on a tough 19-mile course.

Should I prepare to surrender to backgammon and bocce, or was there still hope for my lifelong addiction to biking, skiing, climbing, and other outdoor activities and races?
