The only other change since Thanksgiving was adding in more strength workouts, specifically squats and lunges. I was inspired to increase my strength workouts from this paper:
Louis et al, Strength training improves cycling efficiency in master endurance athletes, Eur J Appl Physiol (2012). Not a huge group size, but the results were remarkable.

Since EF uses NP in the numerator, shouldn't it use something like TRIMP in the denominator?
Those
power:HR graphs are from intervals.icu. It looks like it's using average power, but I'm not sure.

~3600 feet to 6500+ feet. Total time about 1:15 to 3:00. The 3-hour sessions make my sit bones hurt, so I tend to avoid them.
One other item I've noticed -- virtually zero cardiac drift on these long climbs. That's new.

I don't know. I still have days where I feel like I need a rest, so these workouts aren't fatigue-free. I'm riding in a cool room (mid-60s F) with a good fan, so no real heat training.
