5. LaShawn Merrit
2 Gold Medals
If Merritt wins gold in London, he’ll join Michael Johnson as one of two athletes in history to win consecutive gold medals at 400 meters. He’s also looking to shatter Johnson’s world record in the event (43.18 seconds). “I have to leave it all on the track,” Merritt says. “I’m focused on having a great year defending my titles and bring two golds back to the United States.”
