Its probably me and having not read (found) all resources on this topic but currently I do not fully understand how TR is addressing weaknesses / limiters.
I think all would agree that working on a limiter is prerequisite to ride strong during a race so limiters should be definitely taken off during training.
Lets say for example ones weakness is anaerobic power and training for MTB marathon. So following Sustained Build and Marathon Specialty as outlined here is assumed. Obviously, doing Short Power Build or General Build (or even XC Specialty) for addressing weakness is no option as the duration of XCM races will be 3 hours and quite longer (which requires Sustained Build / XCM Specialty phase per recommendation).
What I´ve seen so far on TR for addressing the limiter topic is the following:
Adjusting your training plan – Too much time
Add an extra base and build block (Base/Build/Base/Build/Specialty) and address the limiter during first build block (increased season length by 14-20w)
- Choosing your training plan - Re-build, Off-season, or Maintenance for Your Fastest Season – Off Season – Off-season focus on a limiter
Both options will address ones weakness long time before an A event. Regarding option 1 there will be 28w between training weakness during extra build black and the A event considering following the standard training cycle with base/build/specialty. Quite the same for option 2.
What I´ve also read here is that for maintaining fitness its required to train once a week anaerobic power. But if I train my weakness as described above long time before my A event, all benefits gained will probably be lost and gone at time of race. Also the recommended training cycle (Sustained Build / XCM) does not consider anaerobic workouts that much (2 in Sustained Build Phase, 3 in XCM Specialty – so just 5 anaerobic workouts in 16w).
I understand that anaerobic limiters are on another level for XCM than for a Crit Racer but it will remain a limiter avoiding one to show best performance.
So I basically do not understand how the concept of limiters can be tackled by using TR.
Sure, you are welcome to correct me and / or provide an explanation even I am able to understand
