Good luck! What's your current mileage per week? How old are you? What is your weight and height?
I'm no coach, but here is a typical week for our XC team, which does relatively low mileage compared to other teams, so something you should be able to handle without too much issue right off the bat.
Monday: Long slow distance - 50 min (beginning of season) -> 80 min or longer (pre-end of season taper) - easy pace (build aerobic efficiency)
Tuesday: Speed work - ex: warm up 1 mi + 4x800m fast w/ 2 min rest (probably would be run in 2:45/2:50 for you) + 4 x hill repeats (sprint up, jog down) + 1 mi cooldown
Wednesday: Aquajogging/plyos - lift or whatever you normally do, you have more to worry about for the PFT than the 1.5 mi run
Thursday: Tempo run - 3-5 mi at maybe 70-75% of your effort for 2 mi
Friday: easy day - 3-4 mi easy, w/ 150m strides every mile or so
Saturday: race - might want to do another tempo run?
Sunday: rest
Given the low mileage, these workouts tend to be relatively quick and might give you enough time to fit quick lifting/calisthenics sessions in in preparation for you PFT even on days when you run. I'm hoping someone else can give you a better model plan than this, but hopefully this works as a start.
