For me, over-unders don’t work out very well outdoors. I’m either too far over, or too far under. And I end up watching the power meter more than I watch the road. I’d go by ‘feel’ rather than the power meter (get above threshold, then ease up just a touch for the under).
The other workout types are fine outdoors unless you think you need to hit the exact power.
Here is Palisade indoors:
And here it is outdoors (not very pretty lol):
Obviously, there’s effort involved in getting to and from my workout area, which adds to the TSS.
