Thanks for the feedback!

Makes sense on the using a lower gear, as I've definitely noticed exactly what you talked about. My first few rides back in the early part of the year I was losing ability to put out power after less than 60 min, and that was at an effort I would certainly call easy. It's been getting better though, and I'm getting closer to reaching that point where I can really hurt aerobically on the bike the same way as in running.

I think I'm getting you on the training, just to check...something approximately like this

M -60 min very easy
Tu - 90 min w/middle 60min strong but controlled
W - 60-90 min easy w/ 10x30s on, 30s off
Th -2-3 hr easy spin
F - 90 min over varied terrain, throwing in some hard efforts on hills
S - Off/XT/Very easy spin
S -3 hour easy

I don't mean that as a strictly rigid time/day schedule, more just to make sure I'm understanding you correctly.

One other question....group rides. I could see that being really fun, but the downside is I know next to nothing about cycling in a paceline, nor do I know what to expect as far as ability goes. Is it worth finding a good group to ride with once per week, or should I wait until I have more experience for that?
