Hello, i am not sure this is right place to ask it but i have confused about vo2max and fatigue situation.
Today i did Pisgah+6 which is two sets of 4x4´ 102% ftp followed by 30´ 65%.
My heart rate was low (my max 180-182 but my 4 mins lap avg hrs were 157-159 range) i guess it is because of fatigue ( i feel good but my legs were really tired i felt).
So my question is that my heart rate was low and after the workout my vo2max became 64. So can i count it as a pr (or its just because of fatigue and your vo2 did not increase?)
