It seemed like a good idea at the time.
Becalmed by Coronavirus lockdown, I decided to shake things up a bit and try a workout with Zwift instead of TrainerRoad. Bright lights, colorful scenes, large friendly fonts and all that. The bloody thing just could not control my trainer properly. Erg mode was just not responsive at all.
Mind you, I got some personal records by doing 800W when the target was 120.
So it’s back to TrainerRoad for me. If it ain’t broke, don’t fix it.
