Exercise

I have to be able to run 1.5 miles in under 16 min., do 43 sit-ups, and 13 push-ups. I am really close to all those numbers, if not better. The only thing I am worried about really is the running. I can run it no problem, when my left leg isn't injured. This last winter I got tendinitise and I am now trying to get over shin splints. Does anyone know a good way to heal from shin splints? I started using a this rolling thing on it before I run and that has really helped, but every now and again it just aches. I hope that I get it healed before my first PT test. I am suppose to have one at least 30 days before I ship out and well, we really don't know when that will be for sure. It is still schedualed for July 20th, but hopefully it will be sooner then that.
