Tonight’s session was borrowed from a mate who subscribes to the alternative online tool.
It was holding tempo for 1 hr with 5 min +10 w then 5 min back down again repeating 6 times.
I was aiming to be -20 rpm cadence, self selecting ave cadence and +20 rpm cadence.
So giving this simple numbers
Interval 1 at 200w at 75 rpm
Interval 2 at 210w at 95 rpm
Interval 3 at 200w at 115 rpm
Interval 4 at 210w at 75 rpm
" 5 at 200w at 95rpm
" 6 at 210w at 115 rpm
" 7 at 200w at 75 rpm
" 8 at 210w at 95 rpm
" 10 at 200w at 115 rpm
" 11 at 210w at 75rpm
" 12 at 200w at 95rpm
SO…the my HR was lower across both power outputs when the cadence was lower/est and conversely my HR was highest when my cadence was high.
My point is if the power is hard drop your cadence I recall a podcast about efficiency - after a deep dive the synopsis was - aerobically to be efficient drop your cadence to achieve maximum power raise your cadence.
Feels like it brings power as the definitive metric into question. And that is pretty much what Inigo San Millan says - HR is the physiological response so use that not power.
Any thoughts?
PS I am aware this is N=1 so I’d be interested in your findings from hours in the pain caves of the world.
