As if you needed reminding, but here's how the yellow jersey standings looked before stage 20.
The odds of Chris Froome being overhauled? Slim. Impossible? We'll see.

That seven is just four now, with three riders, including Geschke, deciding not to bridge the gap. The four 20secs in front are Alexandre Geniez, Lars Bak, Nicolas Edet and Ramunas Navardauskas.
There are seven riders in a small break 20 seconds up the road. Simon Geschke and his beard are there, as is Geniez still. Mark Canvendish is considering moving up there too - save it for Paris Cav.

So, we can't all have gone up Alpe d'Huez, although some of you probably have.

Alexandre Geniez is the first man to make a move and another three riders go with him. There are a few more looking like they will pop off the front of the group to on this steady descent.
Le Tour general director Christian Prudhomme pokes his head out of a car sunroof and waves a tiny flag. That means the 20th stage of the 102nd Tour de France is under way.
The riders are rolling their way to the start line. Chris Froome and Nairo Quinana are shoulder to shoulder. Sunglasses shield their eyes, hide any emotion.
A few other riders are keen to have a small natter. Quintana and Froome less so.
There are 110.5 decisive km ahead.

This is what the Team Sky rider must conquer to become the first Briton to win two Tours.
The 110.5km route initially included a jaunt up Col du Galibier, but a rock slide meant there had to be a rethink and the Col de la Croix de Fer was drafted in.
Will Nairo Quintana go for broke on that first hors category climb, or will the Movistar man bank it all on the final ascent?
Will he give it a go at all, or just protect his second place on the podium?
Chris Froome, champion in 2013, has held the yellow jersey this year since stage seven. By the time he won stage 10 his lead was up to 2mins 52secs and after stage 14 it was up to 3mins 10 secs.
Yesterday, Nairo Quintana chomped 32 seconds off that gap, leaving it at 2mins 38secs.
The maths are simple for Froome - finish within two minutes and 38 seconds of the little Colombian and, barring a disaster in Sunday's procession to Paris, he will be a two-time Tour de France winner.
Simple, right?
