Earlier quoted context omitted.

Because it fits by multiplying random variables. It cannot explain why records are improving, i.e. why Usain Bolt didn't live 100 years ago.

It can explain it. Better training and better equipment are (at least) two variables that improve people timings. Maybe a century ago there was an Usain Bolt, just didn't had neither the proper training, nor equipment, and those low factors avoided better timings.

And nutrition of course.

I used to like watching the Special forces selection process TV shows. They would claim that mostly people failed due to mental fortitude. The problem was repeatedly in these shows you would see people who weren't fit enough, whose muscles were not capable of the physical strength and stamina necessary to push like this. Many had trained very hard and were in very good shape but they just couldn't sustain it in the c…

Yes, the mental fortitude is much overblown aspect. Yes, there is this thing as mental fortitude and you can even train it to persist to run hard, especially when you "kick" at the end of a race. But this only helps to a very small degree, the most of the result is due to more mundane aspects like your experience with running, your running efficiency, your aerobic capacity, your additional fat you are carrying with y…

Running isn’t an activity where you need much mental fortitude.

But in sailing in 10 Beaufort or climbing in extreme weather it is all about mental fortitude not physical strength or training. Some people just quit, give up and others stand at the steering wheel for 6 hours despite soaked clothes and blowing gale.

Reminds me of the movie Gattaca https://www.imdb.com/title/tt0119177/ Anton Freeman : Vincent! How are you doing this Vincent? How have you done any of this? We have to go back. Vincent : It's too late for that. We're closer to the other side. Anton Freeman : What other side? You wanna drown us both? Vincent : You wanna know how I did it? This is how I did it Anton. I never saved anything for the swim back. Vincent :…

"There's no gene for selection bias" What a goofy moral. John Henry beat a machine once, died, and then was immediately replaced with 1,000 faster machines. Maybe we should have asked why nobody fought for John Henry to retire with a pension.

> 10 miles every morning Holy cow! That's pretty impressive, I run only like 35 miles a week during the peak of my marathon raining blocks.

>> 0 miles every morning > Holy cow! That's pretty impressive

It might be also a reason for not making any progress..

Why not just take the "metal gear solid" approach to shoplifting instead of trying to outrun the professional athlete?

Because in the first case you're breaking the law, and in the second you're just participating in the shop's event?

I've often wondered how exactly I might increase my sprint speed, in terms of form. I've never met a sprint trainer, so all I can do is just try to naturally sprint, but I'm clearly not very fast and never was. But somehow I don't even know what the fundamentals are. What do you need to do to be fast? The other amazing thing is that marathon runners seem to be faster than I can sprint, and I really don't get how they…

There are tons of tutorials on YT about proper running form.

but according to TFA the shop gives permission to steal?

Can you recommend any particular video that you enjoy or is helpful?

Nitpicking: to truly compare the running times they should use the same shoes and tracks. There is a lot of effort put in to make athletes faster. I doubt Usain Bolt would be under 20s on a dirt track.

There were 20000-year old footprints discovered in Australia [1], the estimated speed of these barefoot runners was comparable to olympic sprinters. [1] https://www.nationalgeographic.com/history/article/20-000-ye...

It could be that those people were just better at running than us. Tech that makes shoes and track more springy makes things measurably faster
