It's the boredom that gets to me on the dreadmill. The right music helps, but sooner or later I'm just mentally done, usually well before I'm physically done. It's also always too warm for my tastes there at the gym. So I tend to do a lot of short but fast runs on the treadmill, trying to get some benefit before I'm too fed up.

I haven't run since last Saturday. It was warm enough this morning outside, but there's enough lingering ice on sidewalks that I decided to head to the gym for the treadmill. But when I started the car, the check engine light came on and I drove to the mechanic instead. Tomorrow, I swear I'll run somehow...
