Charity, most guys (non-runners) will run around a 10:30 1.5 mile, or roughly a 7 min mile. I used to run a 4:50 mile and 8:50 1.5 mile (perfect score for AFROTC's PFT) but that was about five years ago and 30 pounds less, plus I had been running 4-8 miles per day since I was 15 so that made a difference. I was a mid-distance runner in HS (800m and 1500/1600m) so I was conditioned for both the longer runs and the shorter sprint work...most people are not.
Most are coming into their application in a similar shape as I am now...slightly overweight and out of shape (due to a desk job...), and busting out 1.5 in around 10:30 and up to 12 mins. My first practice PRT (at home on my own) I had a 12:30 since I was dealing with severe shin splints from working out too hard too soon - in addition to heart rate and bloodpressure issues - but those all have disappeared with hard work and healthy dieting the past two months. But I'm still at around 10:30, and probably won't get to the nines until another two months or more (and at least 20 pounds less).
9:30 is usually a stellar time for women, and even if I get back to my 8:50 you won't be too far behind me, and you'll definitely have about 95% of the guys and 99% of the gals behind you. If I were all of you, I'd add some variety and swap some of the mileage for some sprint and agility work...too many miles can be a detriment and (like in my case) can cause more harm than good with shin splints and severe fatiguing, etc. I've been doing a lot of cycle work - 8-10 miles a day at high resistance and high speed - and have really found it benefitial as opposed to high impact long runs. If you really want to be a beast physically overall, add some swimming workouts to the routine...say, half mile every other day? That and the sprint/agility work in the others will have you toned better than ever, AND I guarantee that your distance stamina and speed will gain (you'll have more power to kick out and run a longer stride, as opposed to shorter but many, many more strides).
That all helped me break the 5:00 mile mark, perfect score my AF PFT's everytime, and now it's already helping me get back into shape yet again just a month into it (no more shin splints too).....just my $0.02 for this week, lol.
