Day 1 of Swimming at the 2012 London Olympics

Men's 400 Meter IM:

Ryan Lochte

American Ryan Lochte's absolutely dominant performance in the 400 IM was the main headline of day 1 of the London Olympics.  Lochte's time of 4:05.18 blew away the field, defeating Brazilian silver medalist Thiago Pereira by nearly three and a half seconds.  Lochte was first from the opening leg of the swim, and pulled far away from the field in the backstroke leg of the event.  Lochte's world-renowned flip turns gave him a huge advantage over the opposition.  The first major shock of the Olympics was that American Michael Phelps, the two time defending Olympic champion and world record holder in the event, did not medal, placing 4th.  17 year old Kosuke Hagino of Japan who had the fastest time in the preliminaries won the bronze medal. 

Men's 400 Meter Freestyle:

Sun Yang

China's Sun Yang won the gold medal in the 400 Freestyle with a time of 3:40.14, missing out on breaking Paul Biedermann's world record in the event by under 0.1 seconds.  South Korea's Park Taehwan, the defending Olympic champion, led for the first 300 meters and won the silver medal.  Park was disqualified in the preliminaries of the event, however after video review was reinstated in the finals of the event.  The U.S.'s Peter Vanderkaay won the bronze medal in what will likely be his final Olympics.

Women's 400 Meter IM:

Ye Shiwen

China's Ye Shiwen put on a tremendous show in winning the gold medal in the 400 IM.  The 16 year old broke Stephanie Rice's world record with a time of 4:28.43.  At the 300 meter mark American Elizabeth Beisel had a full body length lead over Ye, who's unbelievable finish left the silver medalist Beisel a full three body length's behind by the end.  Shwen's final 50 meters of freestyle were incredibly even faster than those of Ryan Lochte, the winner of the men's 400 IM.

Women's 4x100 Meter Freestyle relay:

The Australian women won the gold medal with the Netherlands coming in second place.  Despite having the lead after 300 meters, the American women were passed in the final leg of the relay by both international swimming powers.  The Americans have not won this event since the Sydney Olympics in 2000.
