Marlen Reusser (Movistar) won a solo victory on stage 3 of the Vuelta a Burgos Féminas that finished atop the 7.8km climb up the Picón Blanco, at Espinosa de los Monteros, crossing the line 40 seconds ahead of Yara Kastelijn (Fenix-Deceuninck) and 1:17 minutes ahead of Elisa Longo Borghini (UAE Team ADQ).
Reusser had accelerated from the group of favourites on the steepest part of the climb with 4.4km to go, and only Kastelijn and Chabbey could stay with her. Chabbey had to let go a few hundred metres later, and Reusser kept pushing hard, finally cracking Kastelijn at the two-kilometre mark.
