D-Day. This would have been even better as Stage 20, but it's still the most sawtoothed profile of the race... and, in my opinion, the queen stage.

Climbs
The intermediate sprint comes extremely early into the stage and so the start should be furious. The spike on the profile is obviously BS, but there's still some climbing just after the flag drops.
The first climb of the day is the Cormet de Roselend. Even if this is it's slightly easier side, it's still a solid climb, the breakaway will probably be formed here. There's no real flat from here onwards.
The riders will take a short detour towards the end of it's descent, to climb the Côte de la Route des Villes, the first 3.1k of the profile below.
It's immediately followed by the Col des Saisies. How this is a cat. 2 and the next is a cat. 1 is beyond me...
...because Aravis is twice as easy.
The wall that is the climb to Glières will make or break the day. It should be the last chance for anyone who's not Roglic to take time, let's hope this - and the stage - is raced accordingly...
There's still one uncategorised climb remaining, the Col des Fleuries. The ascent and descent are very similar, consistently at 4-5%.
The descent continues into the final kilometer before the road heads slightly uphill to the finish.
