Distance running is limited more by heat tolerance than anything else. Shorter people have a higher ratio of volume to surface area and stay cool more easily.
This is counterintuitive, but for a given shape, the smaller will always have higher volume to surface area. It's why the bitter Arctic bred magnificent giant beasts like mammoths, polar bears, walruses etc. They retain heat jealously.
You've got it bass ackwards. See response #52 for explanation.
