Hi all - thanks for the tips. I'm about a week out, although I didn't ride EVERY day like I thought I would. Still, I can see some improvement already. My quads still burn when I ride, and I get a little jittery afterward, but I'd say I've progressed from "puddle of goo" to just "mushy but vertical"
I really like biking, but I'm a little skittish of the cars and the big snow ruts. I didn't fall off at all today though! The route I take isn't very long at all - it takes about 15 minutes, and I probably don't go over 10 mph. So all told, by dividing it into 2 15 min sessions it seems to be getting better pretty fast.
I have a really good bike seat (I think) that is super squishy and kinda has shocks so I don't bruise, um, back there.
BP - scary accident? I'm glad you are OK. Thanks for the tips.
