I’m in my second week of sweet spot base mid volume 1 and did my first ever over-under threshold workout yesterday (Tunemah). The last set of over-unders was absolutely horrible, but I somehow managed to complete it without reducing the power.
What worries me is the heart rate I’m seeing during these types of intervals. My max heart rate is about 197, and during Tunemah my heart rate ranged from 175 to 182. Thats about 92% of max HR, which seems really high for this intensity (almost in the anaerobic zone, right?).
Is this something I should be worried about? Should I reduce the intensity of the workouts? If nothing else I guess its a prime example of why you should use power over heart rate as a metric for training…
I should probably note that I haven’t gotten around to buying a fan for my pain cave just yet, and I was sweating buckets during the workout.
