We're staying in a condo complex with a nice gym this month, so I have done a couple of walk/run interval sessions on the treadmill. Since I haven't run in over a year, I started slowly with just 2 miles total. First time was 3/4 mile run, 1.25 mile walk; and today I did a full mile run alternating with walking periods. Feel pretty good for just getting back to it, but I'm taking it slow, just 5.5 mph for the walk, 4 mph for the walk portions.
