I’ve started TrainerRoad in October 2019 and have only trained inside every since.
Today, is the first time I went outside an man what have I improved, I couldn’t believe it (yes, I checked wind speed and direction).
Immediately, I could easily peddle 35km/h (instead of 29-3) without my HR going up extremely. And the part about repeatability is also really true. I had a couple of wind sections, and after that my legs quickly felt fresh again, where previously I would struggle and my power would slowly drop over time.
Really, this only motivates me to train even harder and stick to TR training plans.
TR is great!!
