I looked at his Strava file and Lenny Martinez cracked completely in the end. On the final 28:36min of the stage he only did 202W. Even at his weight of only 52kg that's under 4 w/kg.
Edit:
55kg Ciucciarelli cracked even worse and did only 190W on the final Bormio - Santa Caterina sections. Looks like many went too deep on the hard climb, only to totally blow up afterwards.
