I just rode my trainer for one hour straight spinning at 90rpm's... I only started biking last spring, and have been really lazy about riding the trainer (or outdoors for that matter) all winter, so I had no idea if I could ride that long at a continuous cadence. I put on a Podrunner track at 180bpm and just went for it. It was actually fun... I read my new issue of Bicycling while at it.![]()
