you will eventually get a sense for which workouts you need to be fresh for in order to get good quality and which ones you don’t. For me personally, any workout with a lot of time above threshold is ‘hard’ and i can do much better if i’m fresh. a long workout that’s pretty easy but long might have high TSS (which remember is just maths) but is generally completable no matter how tired i am. So yeah, maybe use IF as a rough guide until you figure it out.
Those who know me know that i am a huge proponent of individualization. TR is not your coach, they can never really know you or how you will respond t oworkouts, how much recovery you need, etc. So i’m all about, modify things as is required in order for you to get the benefit that you’re trying to get.
Big caveat though is that you gotta look at everything in context and sometimes the order IS there for a reason. For example, if you have hard day, hard day, long day, hard day, it’s pretty much expected that quality will be low on the final hard day. However, the plan could have programmed that way in order to get you used to trying to perform under fatigue–to sort of simulate what it’ll feel like in the last hour of a six hour MTB race, etc. To compensate for lower volume overall by giving you an “alternative way” of learning how to perform under fatigue.
So keep that kidna thing in mind as you move things around.
