New Paradigm for run/walk

I have a new paradigm now that my treadmill is here and functional.

First of all, I'm really surprised by a) how much I really love the thing; b) how functional it is to take out, walk on, and then put back out of the way; c) how easy it is to walk and either listen to loveline (or my iPod); or simply watch TV.

So, my new paradigm is that when the TV is on, then I'm walking on the treadmill. (I recall a story about an engineer who hooked up an exercise device that his kids needed to use to watch TV). Further, I also intend to try to maintain 20 miles per week, combined running and walking -- I may up it to 25 miles at some later point. Currently goals are to run 11-13 miles per week. . . so that's only 7 miles per week of walking which is slightly more than 1 mile per day of walking (generally comfortable walking pace of ~2.5 mph which is roughly 24 mpmiles -- essentially a seinfeld episode).

Also, I like to walk right before bed (an easy mile) -- it, umm, seems to naturally aid in my digestion. . .

According to this calculator I burn approximately 162.3 calories per mile (@ 3mph or 20mpm).
