After the fireworks of yesterday the race looks very different from the day before.
Jai Hindley (Bora-Hansgrohe) is now in the yellow jersey and has a quite commanding lead, while Tadej Pogačar (UAE Emirates) lost a minute to his presumed big rival Jonas Vingegaard (Jumbo-Visma).
It's anyone's guess what will happen on today's stage which features three mountains including the fearsome Col du Tourmalet.

Recapping a classic mountain raid
Yesterday's stage was truly one for the ages with Jai Hindley soaring into yellow thanks to a good old mountain raid whereby he got in the break and kicked on from there on the final climb to put himself 47 seconds to the good.
At the finish he said "it was an accident". However, its noteworthy that he recced these stages months ago. It was no accident that he knew what he was doing, made the right moves at the right times and maximised what he could get from the day.
The other winner was Jonas Vingegaard, who put Tadej Pogačar to the test and found him wanting to the tune of 1-04 in fact.
Can the Slovenian hit back today? Can Bora-Hansgrohe do an effective job of defending the jersey? Will Vingegaard show them all who's boss?
Welcome to the second day in the Pyrenees.
Who is Jonas Vingegaard?
Several months ago my colleague Tom Thewlis embarked on a mission to profile the reigning Tour de France champ.
The result is a highly insightful feature with sotires you won't have read anywhere else. It ran in our Tour de France preview magazine but we've put it online this monring.
I encourage you all to go and read it.
How tough is the Col du Tourmalet?
Pretty tough with the steepest ramps towards the top.
This is its 85th appearance in the Tour.
The first over the summit will be given the Souvenir Jacques Goddet, a cash prize of €5,000, given in honour of the long-standing Tour organiser who died in 2000.
