Of the early riders, by the far the quickest proved to be Groupama - FDJ's Lenny Martinez. The Frenchman clocked 31:40 when he crossed the line, 59 seconds quicker than anyone else who finished their efforts to that point. The next man into the hotseat was Luke Dudbridge, although the Australian wasn't able to get too comfortable as first Nils Politt and then Stefan Bissegger went ever quicker. The Swiss rider having the new benchmark time of 30:06.
Whilst Bissegger's effort looked like ensuring a relatively lengthy stay in the hotseat for the Swiss, Kevin Vauquelin had other ideas. The Frenchman, who has already taken a victory on stage 2, became the first rider to go under 30 minutes with his time of 29:44. After spending a fair while as stage leader, Vauquelin was eventually narrowly unseated as Victor Campenaerts went
less than a second quicker.
Stefan Kung then looked as if he would threaten the time of Campenaerts. Mid-ride though, the Groupama - FDJ time trial specialists saw his chain slip off momentarily. A potentially key factor in denying Kung the new fastest time as he crossed the line 8 seconds down on Campenaerts. Wout van Aert gave it a go, but was nearly a minute slower than his compatriot at the line.
Julien Bernard, riding on home roads was
given a hero's welcome by a legion of his supporters on the day's only climb. It was Ben Healy, who was the next rider to threaten the Lotto Dstny man in the hotseat. Fading somewhat in the final run in however, the Irishman eventually finished 7 seconds down. Derek Gee also made a solid effort, stopping the clock 25 seconds behind Campenaerts. When the big four of Primoz Roglic, Jonas Vingegaard, Remco Evenepoel and Tadej Pogacar took to the course however, Campenaerts was still in the hotseat.
As soon as the big 4 were on the course however, the timings were almost immediately turning green, making it unlikely Campenaerts would be able to hold onto the stage win. At the first time check, Evenepoel was the fastest, 2 seconds clear of Pogacar, 10 to Vingegaard and 20 to Roglic. At the second check, Evenepoel had increased his lead over Pogacar to 10 seconds, 23 seconds ahead of Vingegaard and 37 seconds faster than Roglic.
Crossing the line, Roglic took the provisional lead, over 17 seconds quicker than Campenaerts. The stage win wasn't forthcoming for the BORA - hansgrohe leader however, despite Vingegaard dropping to 3 seconds slower. There was then a moment of concern for Evenepoel as the Belgian suffered a minor mechanical with just over 2km to go. Nevertheless, he crossed the line in the provisional lead, 34 seconds quicker than Roglic. Would the gear problems prove fatal for the stage win though? As it turned out, no. Pogacar crossed the line 12 seconds down, missing out on the stage but keeping yellow.
