Thanks so much for your input, makbike!

I took my son to have all 4 wisdom teeth removed this morning (he's 16), so there was definitely no bike riding earlier today.

I did finally make it out onto my trainer for 47 minutes this afternoon. I definitely think the trainer seems a bit more difficult. My dang iPod was dead, so I hauled out my Bose stereo system to the garage where our home gym happens to be. I cycled to Marvin Gaye. I knew I couldn't keep going nowhere without at least some music. I now know I definitely have to buy a standing fan! I sweated like I never have before.

I have another question. I need a simple rear wheel cyclocomputer. I'd just like to know distance and average speed. Any suggestions? I have a Sigma cyclocomputer on the front wheel, but of course that's not turning when I'm using the trainer.

Thanks!
