Thanks, all, for the feedback. I should have mentioned that I fall in the "heavily muscled" classification. One of my twin sons is a Cat 2 and he's basically 190 lbs, identical height and build as his dad (except for the weight). No doubt with some discipline I could get to 185. Once I retire (soon) I should be able to get the mileage up to 100-150 pretty easily. For now I'll have to focus on a longer long ride and let the chips fall where they may during the week. I can ride during the week when I'm not traveling since I work out of my house, but can't do much more than a 20 mile ride.
