I have noticed sometimes when I switch a workout to an outdoor workout, particular recovery day workouts, that it will adapt the workout to one with a slightly higher PL:
TR doesn’t have 1 to 1 exchanges for every workout swapped to outside, so you’ll likely get a workout that’s close enough. Also, TR likely expects outside workouts to have interruptions (stop signs/lights, traffic, etc.) and compensates for that in their workout suggestions.
