Thanks everyone. Lots of good advice/suggestions here. I have a power meter on my bike so I can use that to start structuring some kind of workout. I also know my MAP and have translated that in to my FTP. So I have those numbers. Now I just need to get a workout plan going. This is where I need some help.
I like the idea of doing 80:20. That is 80% of my ride are easy while 20% are hard workouts. A challenge will be finding an area where I live that I can get an extended workout/ride in, but one thing at time.
Are there any free online resources for designing workouts? I will try to post a power curve/time in zones from my last ride when I have a spare moment. Thank you.
