Trying out a Zwift training plan and while I appreciate the varied power/cadence combos the extended low rpm kills my knee. Is there a way to work around that and still maintain the zone and get my all important gold star? 
I don’t see a way to edit cadence or even see what it will be before the workout starts.
You don’t have to hit the cadence zone to get the gold star.
Thank you so much! Wow, am I a perfectionist about the numbers and gold stars or what? Thanks for the link so I can learn lots more too. I appreciate your helpfulness.
