Not sore but climbing stairs was a little achey. Of course, over the years I've always felt a bit of that whenever I exert myself cycling. The more I think about this the more I think only fluid retention could result in a 2 lb. gain in such a short time. FWIW during Saturday's ride I drank 2+ large bottles of water with GU tablets. And, after the ride I drank the remains of the third bottle and 8 oz. of chocolate milk.

With regard to calories burned during that ride it is hard for me to believe the low numbers some propose. I have researched this on sites as diverse as Bicycling.com to the Mayo Institute to many other medical/nutrition sites. All the results on those sites would indicate a much higher calorie expenditure. I am not a scientist or professional in the field but have been a serious athlete and do have a "sense" of it.

What it amounts to is my really wanting to understand how my body functions at this age. It seems much different than what I have known before I hit 50 or so.
