Another Run Day 4

Well Today was not the best but I knew I had to run to keep it going.  I was stuck in a meeting until 5 so I didn't even get out of the house until close to 5:15 to go run and the sun had already gone down so my time was limited.  I ran a 3 mile loop however I only ran the first two miles because my knees started hurting, not sure why.  I think I need to start doing one legged squats again to strengthen them.  Tomorrow I have another morning work out so I hope it goes well.
