Less meat to him, so likely quite a bit more aero but:
At 75kg, MVDP was doing 5.84w/kg normalised for the last 1.5h. After 3.5h of racing.
I imagine the lighter Bernal and Alaphillippe would have been needing to hold more than 6w/kg to match the power disadvantage. They were taking turns, and not just tagging on.
The big focus on nutrition, hydration and timing have got to be one of the big improvements.
400w would be burning 1500 kcals an hour, at best 400 kcals of carbs an hour in.
Maybe 1.5l of sweat loss an hour?
