Chinese swimming athlete Wu Peng won the 200-meter butterfly at the Charlotte UltraSwim long-course meeting on May 14, 2011, by defeating U.S. Olympic champion Michael Phelps, who reigned in the 200-meter butterfly for nearly a decade.

This is Wu's second victory over Phelps. On April 9, 2011, Wu's victory over Phelps at the Michigan Grand Prix marked the 14-time Olympic gold medallist's first defeat in the event since 2002.

Wu, 24, was born in east China's Zhejiang Province. He started swim training at the age of 5 and entered the provincial swimming team in 2000 and national swimming team in 2001. In the 2002 Busan Asian Games, Wu became champion of 200-meter butterfly, 200-meter backstroke and 400-meter medley relay and gained immediate international fame.
