what regt you joining anksy, i start recruit training for marines in 7 weeks 
my best run time in 1.5 mile was 8.55 and time at lympstone was 9.17 need to start trainig properly but i am not a very fit person, 1.5mile / 3 miler seems to be a lot of mental strength in addition to some fitness.
person who came first in run in my prmc was 16stone 6'1 and a big upperbody imo lot of people bring in body mass as an excuse
