That's something I've been trying to balance. I've started some of the training plans previously, but never completed them, in part because the cumulative effort of 5 days commuting plus the workout sessions can be a bit much as my base commute is about 100TSS per day.
This winter I'm planning on changing my approach, and running the commute as my base training sessions, and then put in 1 threshold session, one hour + 90% effort and one higher intensity session. In practice this means that whilst I may follow a training plan, I'll do no more than two of the sessions - so if I was following the 4 week booster plan, I might do the Day 2 and Day 5 of week one in the first week, and then day 2 and day 6 in the second week. Plus say an ascent of Alpe Zwift as a free ride.
If I'm doing a longer weekend ride, I'll probably skip all the sessions for that week so turn a 4 week plan into maybe a 10 week plan.
