Michael Phelps returned to action over the weekend, competing at the Charlotte UltraSwim in North Carolina. The 14-time gold medalist won three of four races, but narrowly lost the 100-meter backstroke to local trainee Nicholas Thoman.
The Olympic superstar did not sound particularly enthusiastic after the competition, describing his weekend as "not great, not terrible." He also admitted that he has room to improve. "I'll be the first to admit my training isn't where it should be," he said. Scroll down to see Phelps at the event.
