It is said that the Yellow Jeresy gives a rider wings. That may or may not be true, but it did help Lukas Postlberger (Bora-Hansgrohe) laid down a great ride in today's time trial. The Austrian started the day with a two second lead over the sprinter, Sonny Colbrelli. The Italian wasn't too much concern in a hilly time trial (although he did an excellent ride on his own), but the GC riders were all hunting both the stage victory and to take over Postlberger's yellow kit. So it was that Alexey Lutsenko (Astana-Premier Tech) took the stage, but wasn't able to dislodge the Maillot Jaune. Postlberger will start stage 5 still in yellow, but only by one second. And the others are lining up behind with the main contenders all within a minute of the current race leader.
