Running on the Treadmill

I know I have not been terribly transparent with my runs recently. So in the interest of full disclosure, here is my schedule.

Monday: Downhill
Tuesday: Basic hills
Wednesday: Speed
Thursday: Random hills
Friday: Downhill

Downhill: Downhill for twenty minutes, uphill for a minute or two. Repeat.
Basic hills: One minute on, one minute off. (This is the treadmill "hill" function.)
Speed: Two minutes on, one minute off. (This week, three minutes on.)
Random hills: This is the treadmill "random" function.

p.s. The treadmills I use are Life Fitness models 9700 HR and 97 Ti. They are tremendous.
