Peter Nickles‘ average day lasted longer than yours: He got up at 4:30 a.m. and went for his traditaional swim. Nickles, famous for marthoning and triathloning—-and also Blackberrying, even at 70!—-has had trouble with his knees in recent days, forcing him to quit running. After embarkring on more biking and swimming, however, “my knees are feeling better,” he says. 

There could be a comeback!
