One thing with this stuff I'd like to learn more about (thinking about our KJ conversation) is perhaps what workouts are optimal NEXT after the workout you just did for specific examples.
I feel sometimes it wouldn't matter a whole lot. But other times it may.
Example:
Tuesday I doubled up. I hadn't ran in a while, so ran for 45min at lunch. Zone 2. Felt great, felt easy. Tuesday night after a good meal I did my 40/20 workout. A tough workout. Lots of Z5 time. 165 TSS in a day for me is a lot. So, the smartest move was take an off day yesterday. I made sure to walk a good amount at lunch on the off day, did some plank/pushups, stretched, used the foam roller. Now..........today. I'm thinking, what would be "optimal" after a day off and the 40/20's. I don't think another super tough high intensity workout would be in store. I'm thinking probably just 2hrs Z2 free-ride on Zwift tonight.
It's that kind of thing I feel I could do better at.
