Dear TR experts,
I started TR in January after a decade or more of drinking, smoking, and all other kinds of unhealthy habits. Needless to say, it was time for a change. I’m very happy so far with both the app, community and my personal progress. I started out with an FTP of 177 and have brought this number up to 220 (used ramp test in the beginning but I’m now using the AI since they are so close to each other).
In the past few weeks, however, I have been broken by some workouts and outside rides where my HR seems to skyrocket, regardless of the interval effort. Determination is not the issue here, I find myself having to abort intervals because otherwise, I’d faint. The strange thing is that my legs don’t feel heavy or exhausted at all, it’s almost as if my heart just can’t follow my legs. To give some numbers, my rest HR is 48, my max HR is 205, I rode an interval today where I was at 195 for 10 minutes at which point I started seeing black spots and had to lie down on the floor barely remaining conscious.
I’m a bit at a loss on how to proceed, I’m failing workouts and am left with low morale while my legs feel fit. Does this mean I should focus more on Z2 work, longer but less intense workouts? Is my FTP too high, even though it doesn’t feel like it? Could this be due to nutrition?
FYI I know nothing about the science behind all this, even FTP is a relatively new concept to me so any advice would be greatly appreciated.
Thanks in advance!
