A-17. Sound judgment must be used in the selection of a 2-mile run course. There is no requirement to survey 2-mile run courses; however, selected test sites should be free of significant hazards such as traffic, slippery road surfaces, and areas where heavy pollution is present. Running tracks may be used to administer the 2-mile run event. If a 400-meter track is used, the OIC/NCOIC must add an additional 61 feet, 4 inches to the standard 8 laps to ensure the test’s required 2-mile distance is covered. One lap on a 400-meter track is 92 inches shorter than one lap on a 440-yard track. Eight laps on a 400-meter track is 736 inches shorter than eight laps (2 miles) on a 440-yard tack. Therefore, Soldiers running on a 400-meter track must run an additional 61 feet, 4 inches.
As to the question about width. You would have to specify your situation. Yes I understand on a track that there is a big difference in a standard lap distance from inner lane to outer lane, but nothing forces you to run the outer laner so the width isssue is not considered a detriment to the runner.
Width such as when your running on a street (bike lane) on a busy street you can not pass other runner's because one side there is field and trash which does not allow you to and on the other side is traffic. This causes the runner to ADD time to their mile time. Yes, the runner can speed up but with no energy left the runner infront of you causes you to SLOW down
