Where to start when immediately repeating Jorge's winter cycling programme

Way back when I always repeated in full, had a great jump in CP doing it back-to-back leading into Tri Sprint season at the time.  I enjoyed the VO2 phase the most.  I dreaded the 6x4' workouts!

I guess it depends on your long term focus and your strengths.  I hope Mark doesn't mind me posting the following.  It's some info when he had a mentor power group with coach Shane a several years back, I liked the different approach.  Take a look at the group's archives, some great info and workouts arethere.  I still have all my notes and the workouts archived for importing into TrainerRoad, MaximumTrainer, etc.:

Dr. Phil Skiba describes threshold and VO2max using a house analogy where threshold is your ceiling and VO2max is your roof. If you want to increase your power at threshold, then you need to have sufficient attic space in order to raise your roof and if your threshold and VO2max are close together, you will first need to raise the roof (increase power at VO2max) before you can push up the ceiling.
Depending on the athlete, the difference between power at VO2max and power at threshold will vary and depending on the difference between these values, we can focus your training a bit to address your limiter. In order to determine how to move forward for each athlete, we are going to look at how your short and long tests compare and then decide from there how to proceed. While the ratio between the two will not provide a hard and fast answer, it will provide some guidance and then, combined with your training over the coming weeks, we can decide whether you should stay the course or make further adjustments.
In order to determine the way ahead, you are going to divide your short test power by your long test power and then use the result in order to determine which workouts would likely be best for you this week. You will notice a bit of overlap with the numbers and if fall within the overlap, then you can decide which set of workouts you think would be best for you (and of course we can help steer your decision).

Short test to Long test ratio result is <1.1 (group 1, aka the TTer’s, work the short term power)
Workout 1 – VO2max 1
Workout 2 – Threshold 1
Workout 3 – VO2max 2

Short test to Long test ratio result is 1.09-1.16 (group 2, aka the All Rounder’s, work a bit of everything)
Workout 1 – Threshold 1
Workout 2 – VO2max 1
Workout 3 – Threshold 2 or Sweet Spot

Short test to Long test ratio result is >1.15 (group 3, aka the Sprinter’s, work the long term power)
Workout 1 – Threshold 1
Workout 2 – Threshold 2
Workout 3 – Sweet Spot

I have seen similar improvements on the bike. My last raced I had a 2:32 bike split but it took me almost three years before I was finally able to go under 3 hours.  Jorge's Winter Bike Plan was the first bike plan that I did. I did it out doors after my 2nd race season from June-September  when I had day light on my pre-work rides (I just raced on May that spring).  I had a coach this year and did a large portion on my bike training with the TrainerRoads.  I did my last race about a month ago and am working on goals and training plans for next year.  I also struggle with the short high intensity intervals but feel that the long intervals are too easy.  I will have to look at Mark's archived mentor group.
