A person has a lungful of air and they need to travel as far as possible on that one breath

Falling

Running is more efficient for the same speed than walking fast.

Turtles have natural predators, so they do have good reason to go fast.

Running.

I've done this before. In fact my cross country training used holding your breath and counting as a training technique. Then when you run the race, you breath normally and have larger lung capacity and better use of oxygen. Your body will eat up the oxygen at almost identical rates if you are walking or running, but you can cover a shit load more distance running than walking and holding your breath.

kill yourself and go to heaven with that breath of air
