fwiw - I'm in process of selecting my first road bike at 41 (42 in nov.)... been active for years, got injured in my mid 30's (herniated lumbar disk) while weight lifting, needing to get back into shape, have had a mt bike for decades, used it for commuting to/from the train station, play time with the boys and neighborhood rides with the kids, starting to ride it more for fitness and now am needing a real road bike, I'll be right behind you very soon...
