Still after all his lost in the recently ongoing London 2012 Olympics, Michael Phelps still was considered as the greatest swimmer alive. And as he always wanted to do something that no one has ever done before.

According to the reports, the world’s greatest swimmer cruised through the anchor leg of the 4×200-meter freestyle relay for him to earn his record 19th career Olympic medal and 15th gold on Tuesday night, etching a place in history as the most decorated Olympian of all time.

“It has been a pretty amazing career but we still have a couple races to go,” he said.

And his remaining four days in the pool at the London Games are all about putting that mark even further out of reach. Phelps has three events to go — the 200 individual medley, the 100 butterfly and the 4×100 medley relay. He won’t be racing for a medal on yesterday, when he competes in the preliminaries and semifinals of the 200 IM.

But although pondering the possibilities is a bit silly, now that Phelps has gone past the record. Phelps took the silver in the 200M butterfly after being outpaced by South African Chad le Clos in the final gasp of the said race. (He just lost by 0.05 seconds).

Phelps, who began swimming to emulate his sisters at age 7, set individual world records 29 times, and he still holds records in six events. In the three competitive races he has left he won’t be besting those times, now that he’s almost a swimming old man (and because of slower swimsuits).

He wraps up a career as the most decorated Olympian ever, perhaps the greatest ever. Some commentators will argue the cases of track and field’s Carl Lewis, who missed an Olympics because of a U.S. boycott, or distance runner Paavo Nurmi, who won 12 medals. Some might argue for Bjorn Daehlie, the Norwegian cross-country skier. And there’s gymnast Larisa Latynina, whose 18 medals are now second all time.
