I'm sure the army is tougher then the airforce. In our basic we had to do 2 miles in 18 minutes.. which is a cake walk. And that's only 9 minute miles. When I tryed out for the PJ's.. special forces.. we had to do 5 miles in 32 minutes... that my friends.. is what hell is all about for a non distance runner like me. Almost killed me. You average guy.. not in great shape, but runs occasionally, should be able to run about a 10 minute mile.
