It's him or Rubio on towards the 3 Merlons IMHO!
Whoever holds on for the stage win has won the mountains jersey as well.
It wouldn't be possible for either Rubio or Pinot to win that stage, but still not win KOM? If either Healy or D. Bais gets enough points elsewhere?
Might also be time to start accepting that Pinot's final GT stage win was probably Tourmalet 2019...
