Well, the trainer got put off for another night. I had to work late, and by the time I got home, I didn't want to deal with changing wheels and saddles, so I just walked on the treadmill for an hour. Felt great, but my legs kinda were weird - gave out on me a few times. Guess even just a few weeks of taking it easy takes its toll. I kept the heartrate very low, so everything felt okay.
