This video shows Sir Roger Bannister breaking the 4-minute mile barrier.

It occurred in 1955 and after he finished the race, Sir Roger all but collapsed from exhaustion into the arms of his handlers and admirers.

I wanted to show this because I just watched the end of the marathon race at the Rio de Janeiro Olympics. Eliud Kipchoge of Kenya won the event in 2 hours and 8 minutes.

He just ran 26 miles, 385 yards!

So help me, he looked like he could have kept going another 26-plus miles!

Am I the only one who is utterly amazed at the stamina of these marathoners?
