New to TR, should I be reducing my outdoor rides / TSS?

It’s fine as long as you can do the other workouts ok. Note that as you move through the plans this may be quite a bit more challenging compared to now.

Some alternatives

  • take the Sunday MV workout and replace with longer Z2 outdoors (see weekly tips)
  • take a structured workout outside by pushing to your head unit

What’s your outside Power source? do you do very long or very hard rides? I ask because your outside TSS are similar as indoors.

I also noticed you changed your FTP a few times (presumably you didn’t test that often). You can adjust the workout intensity during each workout if you feel a slight adjustment is needed.
