I am a big swimming fan.  My favorite is Michael Phelps, who is the most awarded Olympian of all time.
He is a legend, unlikely to be matched in our lifetimes. He was designed to swim.
I believe you are right.  He won eight gold medals in 2008 alone!
I watched him win those. He is an extraordinary athlethe.
Michael Phelps
Michael Fred Phelps II (born June 30, 1985) is an American retired competitive swimmer and the most successful and most decorated Olympian of all time, with a total of 28 medals. Phelps also holds the all-time records for Olympic gold medals (23), Olympic gold medals in individual events (13), and Olympic medals in individual events (16). When he won eight gold medals at the 2008 Beijing Games, Phelps broke fellow American swimmer Mark Spitz's 1972 record of seven first
three medals he won at the 2004 Olympics, he is best remembered for his silver, as teammate Michael Phelps overtook him at the very end of the 100-meter butterfly to win the race by 0.04 seconds. Traditionally, the Olympian who places highest in an individual event will be automatically given the corresponding leg of the 4×100-meter medley relay for the finals swim. This gave Phelps an automatic entry into finals for the medley relay but he deferred that spot to the world record-holder and swam the butterfly leg in preliminary heats instead.
