Can’t see the custom workout (gets an error… I think private workouts can’t be directly linked). But the thing about translating a real-world route into TR is the power needed for any given rider will vary wildly with the terrain, weight, and aerodynamics. Eg, a rider with a 5+ w/kg will need the “climb” intervals to be much shorter than a 3 w/kg rider, but then flat-sections your absolute ftp will matter more. And there’s no way to accomplish that in a TR workout for general use. At best you can design the workout around you and your current capabilities, and that’s fine. As you get fitter you may or may not want to tweak the workout to match.
If you wanted to do more of this, I think I’ve seen rouvy lets you build routes on real roads and ride them a bit like zwift.
