I ran again with Sam today. Stairs at Greenlake. The cold kills the lungs. It's a lose-lose situation though, because if you try to suck warm air by pulling up the neckline of your shirt, to thaw your screaming lungs, you get a stitch from breathing too much carbon dioxide. It sucks, trust me.
But we ran 20 of those bitches, up from the 16 we did on Friday. It feels good afterwards, and I know it's excellent for me. It's a great, efficient way to get into muscular as well as cardio shape.
