Pettit outside - double TSS?

Training
7

Because TR needs to fix endurance outside rides?

Here is the outside prescription for Pettit:

Warm Up:

  • Ride for 5 minutes, gradually raising your power from 124 to 149.

Main Set:

  • 81 minutes in between 149-174 watts.

Cooldown:

  • 4 minutes easy.

At low-end of ranges:

  • 5 minutes at 124W (50% FTP)
  • 81 minutes at 149W (60% FTP)
  • 4 minutes at 112W (45% FTP)
  • TSS = 52 (overall IF=0.59)

With main set at high-end of ranges, and warmup/cooldown at low-end:

  • 5 minutes at 124W (50% FTP)
  • 81 minutes at 174W (70% FTP)
  • 4 minutes at 112W (45% FTP)
  • TSS = 71 (overall IF=0.69)

The outside workout prescription for Pettit does not have a TSS of 39, it has a TSS ranging from roughly 52-71+. I’m really not sure what TR was thinking. Calling @IvyAudrain and I know you’ve discussed this in another thread, but IMHO this TSS discrepancy is really confusing.

That is one solution unless the additional time begins to impact future workouts.

If you pedal non-stop on aerobic endurance zone2 workouts, the other solution is to ignore the added time on outside workouts and just ride it for the inside workout duration (e.g. 60 minutes inside/outside for Pettit).
