Evaluating Marathon Training Zones from CPET
I recently had a CPET (Cardiopulmonary Exercise Test) performed on a treadmill during my cardiac rehab. There was no warm-up, and I wasn't feeling at 100%, so the data should be taken with a grain of salt. Nevertheless, I hope the results are still useful, especially for defining my training zones. I am currently training for a marathon, running between 50–80 km per week.
According to the report, my VT2 (anaerobic threshold) was determined at ~173 bpm, which seems very high compared to my recorded max heart rate of 181 bpm. Is such a narrow margin realistic? My lactate was measured at the end of the test at 6.3 mmol/l, which seems rather low.
Is it possible to derive reliable training zones and a specific 'marathon pace zone' from this data?
Results from the CPET are here:
PS: My cardiologists are fine with me running marathons.
