Everyone thought the 100th Tour was over when Britain's Chris Froome tore into the mountains in stage eight, but everything changed the next day as his Team Sky fell apart. Froome still leads but is isolated, and it just goes to show how anything can happen in France.
Here is that week in pictures, boasting the winners, losers and awe-inspiring landscape that has given us all the makings of another classic Tour...
Ostracised: Not quite written out of history, but Lance Armstrong's wins have a long black mark against them. Note several of those around him have also been discredited.
Populu vivu, populu Corsu!
Bringing the 100th Tour to Corsica for the first time was a master-stroke - aesthetically at least. Accompanying the beauty were a few crashes...
Some locals don't agree that Corsica is even in France, let alone part of Le Tour...
For the neutral though, including the island region was a great call...
... Rather predictably, all hell broke loose and the Aussie team was fined.
One is not amused...
Tony Martin also took a nasty tumble, yet elected to ride on and help his and Cavendish's team finish second in the team time trial a few days later.
But even Tony Martin's heroics can't be compared to Geraint Thomas - the Team Sky rider also fell, fracturing his pelvis, but decided to carry on, as his team came third in the team time trial. With a fractured pelvis. Hard.
Amidst all that carnage, there was a stage, which was won by Marcel Kittel. He's happy.
Stage two was won by Jan Bakelants, the youngster's first victory of note. Look at his face!
Simon Gerrans won stage three, the Australian from the Orica team whose bus wrought havoc at the start of the race. And those evil Aussies took a surprise team time trial win too. Coincidence? Probably...
The first three stages were in Corsica, and the South of France was the next stop. Nice. (see what we did there?)
Les Anglais sur la Promenade des Anglais (sort of):
What's French for moo?
Nuns on the run?
There was another major crash, this time in stage five.
The British are coming!
After some excellent performances from the Aussies, it was time for Britain's dominant cyclists to stand up. First, Mark Cavendish banished memories of his disappointing start with a fine stage five win, while Andre Greipel and Peter Sagan also got in on the action.
Meanwhile, Orica's Daryl Impey replaced team-mate Gerrans as race leader, becoming the first South African to sport the maillot jaune.
Only Froome remained from Sky and, while he still leads, the peloton has been truly shaken up.
Week two promises to be enthralling - can Froome hang on, or will the others continue to squeeze him?
