<p>Running is very important; just be sure to purchase a new pair of running shoes approx 1 month prior to USMA - slightly broken in and comfortable. I suggest you consider hiking in those new ACU boots weekly also. My son carrys 40-50 lbs in his back pack and walks/hikes 6+ miles each week. A completely different workout from Xcountry or track running. Now he has totaly new blisters to deal with.</p>
