Don't feel bad, most folks would struggle running a 14 second 100 yard dash. Why do I bring that up? I'm sure the runners in here are familiar with
Nike's "Sub-2" marathon exhibition. Basically, Nike got some of the world's best marathoners together and paced them on a flat course in an attempt to see if a human could go under 2 hours for a marathon. Eliud Kipchoge almost did it -- missed it by only 25 seconds, i.e. less than 1 second per mile.
So here's the incredible part...broken down, Kipchoge averaged a 13.67 second 100 yard dash for the course. Now obviously that's not Usain Bolt territory, not even close, but try to run a 13.5 second 100 yard dash and you'll be sucking wind. Badly.
Kipchoge ran
461 consecutive 13.67 second 100 yard dashes.
