I do probably 90-95% of my rides inside and see good gains in FTP using TrainerRoad, last year FTP topped out at 284 from below 240 at the start.
My challenge is when I get outside I just can’t seem to use anywhere near all my power, for the 19 mile bike leg of my A race Tri, I averaged 227w (80%) when I was trying to go all out. I know coasting will reduce the AP but the NP was still well below my FTP and it always is, regardless of how short the ride is.
As I’m 8 weeks from my A race again, should I stick with only distance specialty or are there specific workouts I can do to get better at holding my full FTP for an hour? Or could it be more a technique issue and I need to get better at riding fast? Last year I was using same power meter inside and outside, on the same bike.
