Not to pick on the only thing I don’t agree with. You definitely have good points outside of this statement. Doing low volume T/W/Th may work in SSB, but i would fail workouts in build phase for sure doing this. Common recommendation is M-W-F for 3 low vol rides and long ride on Saturday. If you can keep from failing those m/w/f rides and add in endurance t/th then do that. This is what i do. On occasion, mostly during build, i will cancel a thursday ride when i just know i’m getting fatigued. Like week 2 or 3 of build.
