Today's workout:

2 miles of hill training. Setting the treadmill to max incline, speed at 3.7 miles per hour.

Going to maintain that until I hit the top of my heart rate training zone (152 bpm), then will drop the incline until I recover.

I'm doing this in preparation for the Super Spartan race in NJ on 9/8/12. The courses are notoriously steep, and I want to be sure that my legs (and lungs) are ready for a long steady climb.
