On the morning of the first Olympic postponement in history, Michael Phelps, the most decorated Olympian in history, made breakfast for the older two of his three sons – Boomer, who will turn four in May; and Beckett, whose second birthday was in February. (Maverick, the youngest, is six months old.) Phelps then lifted weights. Sometimes he rides his Peloton bike in simulated workouts with professional golfer friends like Justin Thomas, Rory McIlroy and Billy Horschel. “I enjoy handing out beatdowns,” said Phelps. “On the golf course, they kill me. J.T. beats me playing lefthanded.” Often Phelps swims, but coronavirus restrictions have closed training pools in Scottsdale, Arizona, where Phelps has lived since 2015.
