All-time record

On August 17, Phelps won his eighth gold medal in the 4×100-meter medley relay, breaking Mark Spitz 's record of seven gold medals won in a single Olympic Games, which had stood since 1972. Phelps, along with teammates Brendan Hansen, Aaron Peirsol, and Jason Lezak, set a new world record in the event with a time of 3 minutes and 29.34 seconds, 0.7 seconds ahead of second-place Australia and 1.34 seconds faster than the previous record set by the United States at the 2004 Olympic Games in Athens. When Phelps dived in to swim the 100-meter butterfly leg, the third leg of the 400-meter medley, the United States had been trailing Australia and Japan. Phelps completed his split in 50.1 seconds, the fastest butterfly split ever for the event, giving teammate Jason Lezak a more than half-second lead for the final leg, which he held onto to clinch the event in world record time. Said Phelps, upon completing the event that awarded him his eighth gold medal and eighth Olympic record in as many events, "Records are always made to be broken no matter what they are... Anybody can do anything that they set their mind to."
