Why not William Marshall:
Did tournaments from his teen years till he turned 40 and never lost one. Unhorsed at least 130 knights at a time when real weapons were used instead of blunted weapons of the Renaissance tournaments. For more see the following:

We do have some records of the achievements of some of the Roman Gladiators (Through the Romans preferred the Chariot races in the Circus). Both the Chariot races and the Gladiators produced some well known (in their time) athletes that equal many of those today.
And let us not forget the Ancient Olympic Games which lasted while into the 5th Century AD (It was believed that the ancient games ended in 405 AD when the Roman Emperor burned down the Olympic Stadium, but recent archaeology indicate that games were held AFTER 405 AD. Thus the 405 AD Act of the Emperor was just showing the withdraw of Imperial support for the Games not an actual ban on them. After 405 AD no written records were kept, but neither was any attempt to stop the games, thus leaving historians with a question when did the ancient games end? ). Many of the Ancient Athletes equal the actions of their modern Olympians, right down to the drugs and other forms of Cheating.
My Point is to keep this to 20th Century Athletes is to restrictive and what about Secretariat and his overwhelming victory in 1973? Why do we have to keep this to Humans of the 20th Centruy?
