3 mile run on the treadmill!

3 mile tempo at 12.5 minute pace - 15 minute warm up at 3.0 plus stretching, 3 miles in 37m 30s, 10 minute cool down with some stretching. Glad I got this one done, but I might only get 2 runs in this week...my right shin is hurting a bit and it is hard to tell what level of pain is concerning for me.  The first few minutes of the run were the worst and then my shin stopped hurting.  Seems like shin splints to me since they got better once the muscle was warmed up and in motion.  I'm going to work hard this next week to get in all three of my runs.  I'm shocked that I can run 8 miles in a week and be even slightly disappointed since I am breaking patterns with every step!
