At the college that I attended, we referred to long-distance runners as “jar heads.” We figured that each day they would unscrew their heads, take out their brains, and then run an unbelievable amount of miles before returning and putting their brains back in their heads.
I say this all in good fun, obviously. I have always admired distance runners and think that distance running is an amazing ability. When these runners race, they set their minds on finishing the race. Lap after lap they strain through sore muscles and tough conditions to finish what they started.
