Olympic race walkers can cover a mile in under 6 minutes, but they have to keep at least one foot on the ground at all times or risk disqualification, a rule that's surprisingly hard for judges to call correctly at that speed.
Walking upright costs humans roughly a quarter of the energy that walking on all fours would, according to a study comparing human and chimpanzee locomotion. That efficiency is a big part of why our ancestors could travel further between food sources as forests thinned into open grassland.
