I did the treadmill today.
5 min warm-up @ 3.7MPH
4 min jog @ 5.2MPH
3 min walk @ 3.5MPH
1 min jog @ 5.2MPH
3 min walk @ 3.7MPH
2 min jog @ 5.2MPH
3 min walk @ 3.7MPH
1 min jog @ 5.7MPH
3 min power walk from 3.8-4.5MPH

Man, being away from the treadmill for a couple of weeks really shows! I had a tough time today!
