Will US swimmer, Michael Phelps' record haul of 23 Olympic gold medals ever be beaten?
The Yanks have well and truly spanked the Aussies in the pool at Rio and Phelps' sustained form has certainly played a big part. The 31-one year old finished his games with a bang on Sunday, helping to set a new Olympic record in the Men's 4x100m medley relay in his final race.
Since diving into the pool as a 15-year old in Sydney 2000, Phelps has shown incredible longevity but is expected to retire after Rio, stating "I'm not going four more years and I'm standing by that". However, after retiring for the first time in London 2012, only to make a comeback in 2014, don't rule out the champion from having yet another crack at glory. Not that he has anything left to prove, of course.
Heck, Phelps' individual gold medal tally of 13 now has him beating even the ancient Greeks - more than 2,000 years ago, Leonidas of Rhodes competed in three obscure track events across five successive Olympics and claimed twelve victories - what else is left for him to do?
Physically, Phelps is a freak.
The swimmer stands 6-foot-4 tall (193cm) but has a 6-foot-7 (203cm) wingspan. The American has flippers for feet, and wears size-14 shoes, while his ankles reportedly bend 15 degrees further than his competitors. Yes that's right, the gold medal-magnet is double-jointed. Did I also mention his lungs are twice the size of an average man? No wonder he can rip a bong.
Phelps' only loss at these games was against Singapore's Joseph Schooling in the 100m butterfly, a man ten years younger than him. Even so, he managed to create a bit of history in a first ever, three-way tie for second in Olympic swimming competition.
Despite that minor blip, the American takes home six medals from Rio, five gold and one silver, to bring his total Olympic medals to 28. The swimmer's tally has him beating entire countries in the medal standings on his own and he currently would be placed as the 12th best nation in the world at Rio. Mind-boggling stuff.
Phelps has embraced his role as elder statesman at these games, spending time to mentor younger swimmers, and believes a more relaxed approach has helped him. Along with other athletes, the 31-year old has also taken a stand on drug cheats at the Olympics, stating "sports should be on an even playing field".
While it would certainly harm Australian medal chances in the pool, there's no doubt everyone would love to see him compete yet again at Tokyo 2020. That's unlikely though, so let's say our goodbyes to Michael Phelps, one of the most dominant athletes ever and undisputedly an all-time great.
