Looking for some advice.
Currently I am doing Sweet Spot Base High volume 2, with some variation in workouts due to real life and boredom, but trying to keep TSS about the same as prescribed.
Recently got HR paired up with ANT+ and did Black Hawk +4 (4 slightly above threshold 10 minute intervals). Don’t get me wrong, it was difficult, but I noticed my average heart rate dropped 1-2 beats for each interval, with lowest average HR on the last interval. I am curious if this is a sign that my FTP is set a little too low?
Do you normally see an increase in HR over the course of 4 above threshold intervals or should it be pretty similar?
