I want to make a joke about why anyone would choose to be a sprinter when clearly that's not our species comparative advantage, but uh... I'm en route to Louisiana for my dad's track meet and his primary event is the 200-meter.
Humans are slower than a lot of animals, but we can run a LOT longer than basically any other animal. The fact we are capable of running marathons is kind of ludicrous when viewed in the context of other animals.
