Polish rider Kasia Niewiadoma did just enough in a thrilling battle with rival Demi Vollering on the iconic Alpe d’Huez to win the women’s Tour de France by four seconds overall.

Vollering was part of a breakaway Sunday with fellow Dutch rider Pauliena Rooijakkers after the Col du Glandon. She accelerated powerfully in the final stretch to win the eighth and final stage.

But Niewiadoma finished fourth to narrowly clinch her first Tour title, with an overall time of 24 hours, 36 minutes, 7 seconds.
