The London Olympic Games has set the stage for one of the fiercest rivalries in competition that will surely leave a lasting memory: Michael Phelps vs. Ryan Lochte.
Michael Phelps, considered by most at the greatest swimmer ever, looks to add another gold medal to his current record of 14 Olympic gold medals.
With the win of his 14 Olympic gold at the Beijing Games, Phelps not only eclipsed legendary Olympian Mark Spitz, but also the Finnish long distance runner Pavo Nurmi and Russian gymnast Larissa Latynina, all of whom have a proud lifetime tally of nine gold medals at the Games.
Ryan Lochte, however, stamped his authority in the men's world of swimming just one year ahead of the 2012 London Olympics when he won five gold medals and a bronze at the 2011 world championships in Shanghai.
At 28-years-old, Lochte already has 47 top competition medals, including six Olympic (3 gold), 19 world championship long-course medals (12 gold, 7 individual) and 22 medals in short-course events (14 gold, 11 individual).
The rivalry between the two magnified at the 2011 world championships in Shanghai with Lochte coming out on top winning five gold medals, including victories over Phelps in the 200-metre freestyle and the 200 individual medley race.
The Olympics kickoff on July 27th.
Men and women's swimming competition is set to begin Saturday, July 28th.
