Not a bad interval day

I added a .5% incline to the first three miles of treadmill training today, and did intervals of 4.0, 5.2, 4.0, 6.0, and so on, until the first three miles were done. This happened in 40 mins by the way, which was good. then I took off the incline and ran .75 mile at 5.2- god it felt better without that little incline. Home and have a couple of kosher hotdogs broiling for dinner.
