My “failure” on my ramp tests have been my legs, they can no longer physically turn the cranks, its not giving up, they will no longer turn the cranks, even if my life depended on it, they are empty! Maybe that is giving up, my legs have given all they can and are giving up?
Heart rate is around 97% of max, 165/171 and know I can hit 171 if I had too… breathing working as expected for that but not limiting me as far as I know as I can breath faster as I have done in the past for other efforts…
I guess its a case of the weakest link in your own personal chain makes a ‘failure’… or maybe more than one link… something has to give up eventually?
Heart Maxed Out
Breathing Maxed Out
Mentally “giving up” I believe is the one we can beat ourselves up with, as the rest of the body was capable of giving more and we know it. For me its the only one I don’t like failing with!
Just some rambling thoughts!
