1. i get on the treadmill and set it to 4.8 miles per hour.

2. i remain at exactly that speed for the duration of the run.

3. i run for exactly one hour.

4. i get off the treadmill and dutifully note total mileage.

5. i marvel at how the number is 4.8 miles, exactly the same as my speed .

6. i drive home pondering what an amazing coincidence that was.
