I'm not sure if I am ready to increase my run time yet. My shins are still sore and I noticed the last two times I ran that my chest was a little tight. But, if I don't increase and push myself than I will never improve. So, despite by concerns my goal for this week:
Run 7 minutes, walk 3
Be on the treadmill for a total of 30 minutes
Do this 3 times during the week
Wish me luck!
