Do taller-people run faster than shorter people?

Yes and no. A tall person will be able to cover more distance with each step, but it will require more power as they have more to move; meaning the tall person may be better in the short-run, but they may tire quicker than the short runner. I'll say yes because the taller runner's legs are longer than the shorter runner,which cause the taller runner to take bigger steps than the shorter runner.
