The important thing is to be recovered for key workouts. It sounds like you weren’t, so you made the right decision. (I probably would have also skipped the pick-ups though.)

If recovery between key sessions is taking longer than planned and interfering with your progression, then reduce the load. That could mean making the long runs shorter and/or the high-intensity sessions lower volume (shorter or fewer intervals).

As you train year after year, you’ll be able to tolerate more, and your recovery will improve.

One more thought on weekly periodization. It’s a good idea to have an easy day before high-intensity sessions but you don’t always need one before long, easy sessions. For example, you could have your higher intensity days on Tuesday and Friday if your longest session were on Saturday.

Unless there’s muscle soreness, the long Saturday session probably won’t suffer from Fridays’ effort. (But the opposite is not true.)
