It seems like the next frontier in distance running optimization is the mind. Given the analysis on the runners' physiology, the only thing that really separated them was mentality.
This seems obvious, given the nature of distance running, but the article never mentions sports psychology or mental exercises the runners do to improve performance.
That's pretty interesting, given that so many elite athletes have put such an emphasis on the mental part of their game:
I knew I was going to wrestle in the finals of the Olympics against a Russian and I knew he had been training specifically to beat me, but then I knew the guy was on steroids, That would help me. Whereas some might think ‘oh he’s cheating, for me you didn’t pay the price. You’re not as committed as I am. It’ll tear him apart. He may be strong, but all I have to do during that 9 minutes of wrestling is loosen one single wire in his brain, make him do something that isn’t perfect, and he’ll fall apart. Besides the health effects, what you lose when you use steroids is mental toughness. The key to victory is that the strongest mind wins. You can get physical strength with steroids, but you lose the mental toughness (you would have gained) from brutal hard work. Steroids hurt mental toughness by serving as a crutch. - Dan Gable[0]
Champions aren’t made in gyms. Champions are made from something they have deep inside them – a desire, a dream, a vision. They have to have the skill, and the will. But the will must be stronger than the skill. To be a champion you must believe you are the best. If you’re not, pretend you are. - Muhammad Ali[1]
Physically is a little bit easier, but the mental part is the hardest part, and I think that's what separates the good players from the great players - Michael Jordan[2]
