There are 70 points left on offer for the green jersey. Bennett has a 55 points lead. That’s pretty safe, but it’s not mathematically guaranteed. So long as he doesn’t crash out he should be fine.
KOM has 11 points remaining on offer. 1 for the Cat 4 climb on the last stage, and 10 for La Planche Des Belles Filles in tomorrow’s ITT. Carapaz leads Pogacar by 2 points and Roglic by 7. Hirschi is mathematically eliminated. Carapaz has a bigger advantage than you’d think, however, because he’s not overly worried about his overall time in the ITT. The mountain points are calculated strictly based on the time taken on the climb itself, so Carapaz sitting in 13th, 4:30 away from 12th and over 10 minutes ahead of 14th (and who really cares about 13th vs 14th anyways?) can soft-pedal the 30km to the base of the climb and blast up the mountain. Roglic and Pogacar will be measuring their efforts for the best overall time. Roglic won’t even be thinking about mountain points. I’m sure Pogacar wants the polkadots, but he wants yellow a whole lot more even if the chances of yellow are very slim indeed. He also recently beat Roglic in the Slovenian TT championship, so he’ll be thinking of a possible stage win as well. Plus he’s already got the consolation prize of the white jersey. His stage strategy will not consider mountain points at all either.
Finally, Carapaz is a really, really good climber. I mean, he won the freaking Giro last year. A single Cat 1 climb that he cares about more than anyone else? I wouldn’t bet against him taking maximum points, particularly in the circumstances.
