> wouldn't be able to sprint a mile, let alone half a mile if we're talking all-out sprint

Can anyone? Almost by definition, your top sprinting speed, e.g. what you would use for 100m race, is going to be different than your speed running a mile, even if you are an olympic athlete.

If you run like you would for a 100m race you wouldn't even be able to complete a 400m race.
