The 1250 watt effort pre-Poggio blows my mind! Imagine a coach said do a 1250 watt sprint followed by 4min at ~6w/kg then 1min at 8+ w/kg 
. I’d get a new coach.
Oh and it’s after 290km.
It was interesting to see how the climbs were done I.e- 5.3 watts per kg ave doesn’t tell the story because he did 11 500-600 watt efforts out of the corners
