Thanks for all the replies.
A little more context about my weekend rides and goals:
My goal: The only discipline I “compete” in is gravel, and gravel races tend to be on the longer side. So the longer days in the saddle are pretty important to me. That said, I want to get holistically fitter / faster, hence starting TR.
Saturday is usually 3-4 hours, at least 100k, mostly upper Zone 2 with some tempo mixed in, and a few very brief anaerobic dips (I live in a very hilly / mountainous area). As I get stronger, the idea is to keep this almost entirely Z2.
Sometimes Saturday will be swapped out for a gravel ride, which is a bit harder (pretty consistently tempo). Sometimes I go a ride with my wife instead, which is way easier.
Sunday’s group ride is sort of 3 rides in one: 45 mins Z2 there and back, and then 1.5-2 hours for the group ride itself. The actual group ride component is generally pretty hard, sometimes “I yearn for the sweet release of death” hard, and I really attribute a lot of my improvement as a rider to it.
Anyway, keeping those rides on the docket is very important to me.
Keeping Monday/Friday as my rest days bookends those weekend days, and serve a double purpose as my weight room days (core, upper body, and mobility work).
I’m honestly kinda shocked TR didn’t automatically rebalance at all when I smushed the days it gave me together to Tuesday-Thursday, and I can’t figure out how to get it to just hand me two interval workouts a week instead of 3 (which seems like the consensus thing to do).
