The only area where I think I'm more vulnerable now is when I add in very intense work. As an example something like micro-intervals. I definitely need a bit more recovery after that type of session than in the past. Same for race efforts. If I don't it ends up being a wash, no real gains. I lean more towards days completely off the bike now rather than "recovery rides", but that is partly an other things in life decision.

Long Z2 stuff doesn't feel that much different if I don't let the ride creep into my 30 yo Z2, eat & hydrate . Power zones are much different now of course. I'm down to somewhere around 8 hrs/week from 12-14, most of that due to demanding job and running a single parent home.
