As I’ve struggled to wrap my mind around 13.1 miles, I came across this article that discusses how the pros push past the pain
It really is mind over matter. Some people may have a slight genetic advantage, but ultimately it’s the people who can push the farthest and the longest who finish fastest.

I think the human body is just naturally lazy, and it doesn’t take long before your legs and lungs are screaming at your to slow down. It’s a matter of rationally overcoming that instinct, knowing that you can go farther and faster, knowing how much farther and faster you can go before hurting yourself.
But that doesn’t make it easy!
