Knees were perfect! No warm up pains. Twice there was a 15 second ache and that's it! I'm working on some conscious form exercises. This helps me to focus on using muscles that improve my form. And it seems to work great!
Tired though, and not much energy. Alas skipping the 3 bowls of cereal before running do tend to slow me down.
Ran 2 miles, 2.5 total
200 each back up/sit ups
10 minutes of planks
100 monster walks
