New to Zwift events and workouts.
Did a workout with ERG mode on. My effort and output were real wonky. At certain points I was pedaling at 95+ RPM only generating 100 watts. At other points RPM was much lower (in the 70s), but watts were much higher. It didn’t really feel like the resistance on the pedals changed despite the workout zone changing. It was nearly impossible to get to watts up and sustained at 175+ lvl.
What am I doing wrong?
