Elite Ironman athletes maintain a VO2 max that is declining during the race, allowing them to sustain a high percentage of their maximum capacity.

“the thing is that what will happen here is that this will actually come down so your V2 Max the V2 Max is declining and therefore it's okay okay that's that's what I wanted to make sure of Cu I was like how in the hell can they hold 4.5 lers per minute or in their case 7.2 L per minute”

“the consequence of aiming for Iron Man is that you want to have min minimal decline in this yes and you need a lower V2 Max because it has to do with priority and training you can't prioritize having like a high one minute power or five minute power simply because it's too far away from specificity of what you really need there”
