A breakaway by 3 riders has lead to a photo finish.
Matej Mohoric must have won the stage by about 1 inch.
Today's stage20 is a 133.5km mountain course between Belfort to Le Markstein Fellering.
To win the yellow jersey, all that Jonas Vingegaard has to do is not fall off.
Thibaut Pinot in his last ever mountain stage broke away from the peloton but was later joined by other riders, Felix Gall, the Yates brothers and yellow and white jersey leaders Jonas Vingegaard and Tadej Pogacar.
Pinot couldn't hold the pace and dropped off and the duel between Jonas Vingegaard and Tadej Pogacar lasted till the finish with Pogacar celebrating a stage win.
The results for the GC will be Vingegaard, Pogacar and joining them on the podium will be Adam Yates. Simon Yates finished in fourth.
Stage21. The final procession from Saint-Quentin-En-Yvelines to Paris.
It's a 115.1km flat course which will only come to life on the Champs-Elysees when the sprinters try to take the stage win.
In a blanket finish between 4 riders, after the photo was checked the winning was Jordi Meeus just in front of green jersey winner Jasper Philipsen
