After spending 30kms in yesterday's break, Dideriksen initially felt the finish in Genep was not for her.
"I think everyone could feel yesterday's stage," she said. "Mid-race, I talked a bit with Amy [Pieters] about who should do the sprint, and none of us felt really super, but Amy said she believed it was a good finish for me. So from there I tried to save energy, and the closer we came to the line the more I got in my sprint zone."
"In the beginning we didn't know if there would be some crosswind sections," said Dideriksen. "But there weren't any ideal places for it, so we were almost sure the stage would end in a bunch sprint."
"But I still covered a lot of attacks because we thought there was also a chance they would let a group stay away today. It took quite a long time before a break went and we had Chantal [Blaak] in it. And in the final sprint, they did a really good lead-out and I'm really happy I could finish it off."
Filled with race favourites including road world champion Chantal Blaak, Hannah Barnes (Canyon-SRAM), Lucinda Brand (Team Sunweb) and Gracie Elvin (Mitchelton-Scott), the day's break in the 129km stage rode under the sceptre of doom until its expected absorption by the bunch came in the closing kilometres.
Elvin's team mate Annemiek Van Vleuten retained the race lead.
