During my last 45 min PowerZone ride, i found that my legs were starting to burn out around the last 10-12 mins. Like zero juice left. It was the ultimate struggle to stay even at the bottom of Z3-Z5. I’ve read people say, “take advantage of your recovery” (zone 1 and 3 in my ride). I was riding at a 34 cadence near the top of my Z1, but some were suggesting 28-30. Will that really make a difference to reduce the cadence in Z1?
