Glad to hear you are back in the saddle. Broke my ankle a few years ago( non bike related) and was laid up for 8 weeks. Then had to convince the wife to let me ride again while she was at work. All is pretty much back to normal now. It does take time ( a lot more as we get older) to get back to a previous level of fitness and weight. I know what you are going through. Keep at it though and you will get where you want to be.
