There's just not enough daylight these days, so the treadmill is becoming my friend again. Last night, I did a small pyramid on the treadmill - repeats of 400, 800, 1200, 800, and 400, with an easy 400 between each. I changed the pace a bit for each distance, running between 7:15 and 8:00 pace for each repeat.
If I'm not going to run often, I'm going to run hard when I do run. Last night, the hamstring bothered me more than it did last Saturday.
Tonight is upper body lifting, and then tomorrow, I'll do lower body lifting before I head out of town for the weekend.
Right now, it's back to software testing.
