Has Anyone Ever Done It - U.S. Sports

Because of the way bolt run's 100 meter dashes, his maximum speed is usually between 70-90 meters, if he ran 40 yards, he would probably speed up quicker.

How about you stop acting like you know anything about running and look at the facts. Usain Bolt, after retirement, went and ran a 4.22 40-yard dash casually in tennis shoes.

I hate when people think that these NFL players are actually comparable to legit T&F athletes. Please remove your pinned comment. (Yes, he may have been wearing sweatpants and a t-shirt, but might I reiterate that he ran that after having been in retirement for quite some time)

A let's run blogger, classic. Even more classic is how he's timing Bolt head on rather than from the side. His timing is just as reliable as the NFL's.

Either way, my point still stands that some NFL guys certainly don't have more speed than Usain Bolt. It's downright insulting to T&F. T&F athletes sacrifice just as much to be successful as NFL players, yet their salaries don't reflect it whatsoever.

Ok yes very convincing Qm, the 4.22 is probably false, but Christian Coleman ran a 4.12, and his record is 9.76. If Usain Bolt's record is a 9.58, then I think he might've been able to run a 4.08 or 4.07

Either Way, the question says sub 4 second, which no one can do today.

Exactly what it sounds like, a 40 yard dash

You run 40 yards as fast as you can. In the US, it is one of the things that moves people up in the NFL draft because speed apparently makes up for other flaws. Teams think if you can run 40 yards faster than the guy covering you, it doesn't matter too much if you're catching abilities are subpar, because you'll be so wide open. This does ignore that rarely people run 40 yards without getting touched in an actual NFL game.

Looking at splits from Justin Gatlin's record, he ran the first 10 meters in 1.84 secs, something which bolt is undoubtedly capable of. Bolt usually runs the first 10-20 meters slower to conserve energy for the 60-100 meters section, meaning that in a 40 yd dash, he would likely run faster in the first 10 yards. Let's just stay safe and give him a 1.75 in the first two meters, and then take the rest of the splits. Giving him 2.75 more, so a 4.50 40 meter dash, which is a 4.12 40 yd dash. Subtract Wind, and you'd be in between 4.15-4.20, which seems reasonable to me. I think the other factors cancel themselves out, such as grass and no sprrings.
