Hi @DennyLK,
I’m Coach Robert. You are doing great with the training so far. What Alex suggests is a good option. I don’t know what your kg/W ratio is, but that could seriously impact your ride.
I always advise you to study the climbing profiles.
Are you a regular climber?
If so, you probably know what you’re up against. If not, this is a serious ride. I did the study for you and looked at the climbing profiles. I also read all the comments to see how others experienced these climbs. There is always valuable information there.
The first climb seems very irregular. You don’t see that on the profile of Etappe du Tour or even on the profile of Climbfinder. But that is the one thing that will kill you on the way up.
The other climbs seem regular, as you can expect from climbing in the French Alps.
You want to know this because you want to know where you will get into trouble. For me personally, everything below 8% is easy. I can do that all day. 10-12% Will raise my efforts to zone 4, which means I can do one hour of that on a tour like that. Everything above 12% will raise my efforts to zone 5, which means there can only be two to three of these parts on a climb, and I need some time in between to recover.
From that perspective, I would do more zone 4 training during the peak blocks. Combined with some VO2 max intervals.
You can do this by choosing the big climbs plan. Use it as a peak block. Don’t change anything if you are a light climber and have no problem in the mountains.
If you are not a natural climber and the mountains are challenging, Change the second peak block by choosing harder workouts and swap the Dynamic force for VO2 max.
These workouts are not harder but different, and they will help you overcome the steeper parts without killing you.
I always use equal gearing in the mountains, which can be 36-36 or 34-34. With that gearing, I can ride anything up to 16%.
Lots of fun cycling
