I have tried the Carmichael program a couple of times and it is pretty intense and I couldn't sustain the intensity for the whole program. At 62 YO my goals are to continue to lose weight, improve fitness and continue to enjoy and look forward to cycling. It seems like I do best with a hard 60-75 min ride once/wk. and 3-4 moderate intensity rides in the 60-90 minutes. Racing, centuries, etc. are not in my program.
