Hills training on the treddy

Today I took my marathon training inside on the treadmill (1, it  rained late this afternoon and it turned out to be quite muggy and 2, I wanted to know and be able to control the elevations.  Several of the treadmills at the gym had some sophisticated training programs pre-set.  I tried the rolling hills program at level 2.

I started with a jog/walk @ 4.0/3.5 mph for 2:00/3:00.  I did that until I reached the 35:00 point.  Then for the remaining 15:00, I pushed the speed up 0.1 mph for both the jog and walk phases (4.1/3.6, 4.2/3.7, 4.3/3.8 mph).  For the last  phase (4.3/3.8 mph),  I jogged 3:30, then walked/slowed down to 3.8 for the remaining 1:30.  The hills were manageable (not too taxing, but gave me a good burn - max incline 1.5%).  I finished with a 5:00 cooldown:

For me, using the treadmill is a good training tool for hills because
I can stay motivated and moving!
