DH, me, and a friend from our cycle club are getting together 2x a week for a trainer class. I think it is 1.5 hours 1 day and 2 the next day. The program we are following was designed by a cycling coach and is designed for Peak Endurance and climbing. We went to the first "class" on Tuesday and it was a doozy!! I am really looking forward to the class and it was fun to do it with a small group. Our club puts on a trainer class that has a large (30-60) turnout, but it is too far away for me to travel from work. We are also going to continue to spin 2x a week and do our regular weekend rides.
