Michael Phelps (R) reacts while shaking hands with Ryan Lochte before the medal ceremony for the men’s 200m freestyle final during the U.S. Olympic swimming trials in Omaha, Nebraska, in this June 27, 2012 file photo. Phelps, who won a record eight gold medals in Beijing, will attempt seven events this time before he retires. In two of them, the 200 and 400 metres individual medley, he will come up against Lochte, who collected five gold medals at last year’s world championships and became the first swimmer to break a long course world record since controversial polyurethane suits were banned.
