All going good for me, been keeping at about week 10 of the plan as that's where I started. Trying to train to HR properly rather than perceived as I did last year. Although I can see why I dropped it last year I'm getting itchy feet staying in zone 2. All my longer session have been hilly sessions so I'm hoping this is going to help. My average bike MPH has gone from 18 / 19 to 14 / 15.
