Very “excited” for you, @PierrePaff! Your list looks “fun”.
As everyone else, I agree that your quest to SUFFer will be very much a personal thing. I chronicled mine here if you’re looking for ideas - especially things NOT to do:
Like I was determined to attempt my KoS at 80%. Somewhere in the middle I crashed…hard…and had to dial it way down to keep going. Recovered enough to finish decently strong but destroyed. I would bet if I went back and averaged all of the workouts, I probably did…75%.
Best of luck! You’ve got this!
