What would happen if you…
- Use Plan Builder
- Schedule all of your weekend rides as B (or C?) events
- Opt for a MV plan,
- and schedule all your workouts for T, W, Th, Sa, & Su?
PB would replace the Sa and Su workouts with your outside rides. And if you accurately estimated your TSS for your weekend rides and matched those to intensity level of the workouts they would be replacing, you might find that your T, W, & Th workouts are not 3-days of intensity, but rather play reasonably well with the outside free rides you have on the weekends.
I’m not sure this is sure fire solution, but it might be worth a shot to see what PB gives you.
