I did half an hour on the trainer today--I put an episode of The Thin Blue Line on and just pedaled, with a break to grab water. Whew. It's a problem when you're squirting yourself with water...I had my fan on full-blast too.

I'm wondering if trainer riding means that things that are comfortable on the road aren't and vice versa. Some of the muscles immediately around my knee weren't happy (and this was at a relatively low resistance), and I'm finding that on the trainer, I'm more comfortable in the drops than I am on the hoods. On the road, it's the opposite.

Equally, though, it could be a function of fiddling with saddle position...
