I’ve just completed this plan on intermediate level with added beginner yoga, beginner strength and mental toughness. I did nearly all of the indoor rides but probably only around half of the outdoor rides for various reasons (life, COVID, my event being cancelled). I added a Half Monty in week 6 because I was smashing all of my workouts.
Overall I found the plan awesome and saw the following gains:
VO2 max (from my Garmin) +5
I’m surprised by the NM increase because the plan mainly focuses on FTP. I think the strength work made a big difference, plus doing the cadence builds (in the past I’ve tended to skip those sessions) and possibly just getting better at the test.
I highly recommend this plan!
