in all seriousness it's difficult to say. there are a lot of formation runs which means you're as fast as your slowest runner. so, depending on your height you will either be in the front (for the tall folks) or in the back w/ the sand blowers (short folks). If you fall in the middle or the back then it really is takes a toll on the shins b/c you cannot keep a constant gate, you have a lovely accordion affect (you go from sprinting to jogging, to tripping on the person in front of you or getting tripped up by the person behind you). On top of all the running you are marching everywhere at super human walking pace, this too is also hard on the shins/legs (especially for the shorter folks).
so as you do your running plans I suggest including sprints, jogging, medium pace and all that into your running plan. Just think you will be running, marching, sprinting, aka moving quickly to get to places quickly for 6wks straight NON STOP - when you hit the rack your body will be tired
