(WALB) - After his success at the 2008 Beijing Games, Michael Phelps had more history to make in London, where he won six medals (four gold, two silver) to bring his career total to 22, making him the most decorated Olympian of all time.
He retired after that, but it wasn't long until he was drawn back into the sport he had dominated for nearly a decade.
Last summer, Phelps posted the fastest times in both the 100m and 200m fly that anyone has swum since 2009 (the year he set world records in both events).
Out of the pool, Phelps has changed quite a bit. Though he is still training under longtime coach Bob Bowman, they are no longer based in his hometown of Baltimore.
Phelps followed Bowman this summer to Tempe, Arizona, where Bowman took a job as the coach for Arizona State.
The 30-year-old is also engaged to be married and expecting his first child this spring.
In Rio, where he would make his fifth Olympic appearance, there are still more ways that he can make history.
If Phelps wins gold in the 100m fly or 200m IM, he could become the fourth summer athlete (but first swimmer) ever to win the same individual event at four consecutive Olympic Games.
