Did You Know?
One of the earliest known odometers, described by the Roman architect Vitruvius, was a gear-driven device mounted on a chariot wheel that dropped a pebble into a box every time it completed one mile, a mechanical ancestor of the step counter on your phone.
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.
