Probably not much use to you at this point, but for future reference - I was getting shin splints from training 4-5 times a week, especially if I threw in roadwork. Do a little reading up about over/under-pronation - just having better knowledge of my feet has totally alleviated my problems (I had to take a break while I had them unfortunately). I also now be sure to stretch my calves thoroughly before and after training, also I don't know the name of the stretch but I kneel down with my feet pointing behind me and gently sit down on the balls of my feet whilst slightly holding my bodyweight with my arms. This stuff all helped me, feel free to correct me if it's bollocks though!
