I received my commission in the USAF through a 4-year ROTC college program.
To graduate and be commissioned, all cadets had to complete the 1.5 mile run. The max times allowed varied by age, sex and any medical waivers obtained.
For me -- male under 28 -- the max time was 12 minutes. For females under 28, it was like 13.5 minutes. Once you were on active duty, you had to pass the test annually. If you wished, you could choose the 3 mile walk rather than the 1.5 mile run. From what those who did the walk told me, it's not as easy as they thought. You can't run at all. You can only walk. And, with the amount of time it takes you to do the 3 miles, you're speed-walking for almost twice as long as you would be running or run-walking.
Since then, the AF has made many changes. in the 90s, they replaced running with a bicycle test while hooked up to bio monitors. I watched in-shape people fail that while others who rarely exercised and smoked everyday pass with flying colors. In 2004, the AF reverted back to the 1.5 mi run.
As members became older, the time limits increased, too. i remember one MSgt about ready to retire could take over 15 min for the run and over 20 min for the walk.
No matter what, females always had lower standards than the males, meaning longer time limits -- yet we had many men who couldn't make the women's run times, and many women who did better than most men.
The mission of the AF is very different than Marines and Army, so the physical fitness requirements are designed more toward aerobics than strength. However, in the 90s when they went to the bicycle, they also added sit ups and pull ups. Recently, they started including a body-mass measurement, too.
The joke was the Army and marines trained to fight, and the Air Force trained to run away!
