How to hit the green zone (Optimal)

Hi there, How do I stay in the green zone / Optimal ? I feel like my training and group rides are hard and fatiguing, but for the last 3-4 weeks i’ve been in the grey and blue zone. I’ve been feeling super good and strong on the bike, but it seems like my fitness curve has plateaued. Any advise? Could it be wrong settings? /Kasper

see if this thread helps..
