Looks like this is a common issue - after my last test my FTP allegedly increased.
When I set the new FTP, my workouts became increasingly harder and I think my FTp is set incorrectly - for example with over/under workouts my HR goes to the max after the first two intervals or so and as a result I can’t finish the workout.
It’s possible that this today’s one was too hard because the previous workouts were harder than expected/planned - I did vo2max intervals at higher power than prescribed and I guess that had a knock on effect too?
I had over a week holiday, which I was hoping would lead to less fatigue but perhaps that contributed to me being unable to sustain the new load?
After how long would you ‘give up’ and retest/adjust difficulty?
Ideally, I’d love to persevere a few more days with a view that somehow, magically I finally get accustomed to the new workouts, but perhaps that is wishful thinking?
