Back in the saddle

Some people at my shop have asked me to join their racing team (more for fun than glory!!) and needed some insight since alot of you are in or have been in my circumstances. It has been a wife, two kids, and 12 years since I trained to race so I need some advice/help on a training program.

I can usually ride in the morning before work and usually in the morning on weekends depending of family schedules and my business travel schedule. I will do some group rides with this team but most of my training will be done on my own. Any advice would be welcomed as I am trying to pack in quality vs quantity.

Thanks in advance as this forum always has great advice and information.
