When the Tour de France riders crossed the finish line on the 2nd stage of the race in 2022, it happened in Nyborg. The stage began on 2 July in Roskilde and drove from there around Western Zealand before passing the Great Belt Bridge. After approximately 18 kilometers across the Great Belt, where the crosswinds had a decisive influence on the stage - perhaps even for the race's outcome - there was only a short run-up section left.
You can try the approximate 2.7 km that the cyclists raced in Nyborg.
