Assume this has been mentioned in one of the 960 posts in this thread, but I’ll ask anyway. I understand that finding VT1/LT1 w/o being lab tested or doing an INSCYD test can be between 70-80% of HRmax for most. It can also be different, I get that. But for those who don’t have access to a lab test we can figure 70-80% right?
Onto my question:
As one gets fitter, how do we account for that increase in fitness with regards to where our HR @ VT1/LT1 goes?
Today I do a VT1/LT1 endurance ride and my goal is keeping my HR within a range of 136-144 BPM and hope that my power falls around 175-195w (FTP is ~310w). I typically see this HR range coincide with this wattage range.
I know that my wattage @ VT1/LT1 will increase as I become fitter, but what happens to my heart rate @ VT1/LT1 as I gain fitness? Does it move in lockstep with the increase in watts?
