I've made sporadic but solid progress in my riding performance over the past couple years, and have recently gotten hooked on the power zone training. Does anyone have a training program for this feature? The Power Zone introduction program is good, but I've advanced beyond it and am looking for a program that recommends # and length of endurance rides, versus regular per week/month, etc. I'm figuring it out, but curious if others have found (or developed) a good program to follow. Thanks!
