Thanks, all, for both the cautions and the encouragement. Sounds like this is what I expected in terms of taking it slowly, listening to the doc and paying attention to my body.

As you all know, it's not just the physical, but emotional/mental health the bike ride brings. It has meant so much to me these last few years I get a little squirrely thinking of doing without (not that I ride hard in the winter much anyway.)

Have a good weekend!
