Cecilie Uttrup Ludwig (FDJ Nouvelle Aquitaine Futuroscope) wygrała trzeci etap Vuelta a Burgos Feminas. Drugie miejsce zajęła Katarzyna Niewiadoma (Canyon//SRAM RACING).
Największe trudności trzeciego etapu Vuelta a Burgos Feminas zlokalizowane zostały w końcówce 117-kilometrowej trasy. Na zawodniczki czekało kilka podjazdów, w tym Alto de Las Hoyas (3,3 km; 5,9%) i Ojo Guarena (1,2 km; 4,9%), gdzie organizatorzy zaplanowali finisz.
Już od startu tempo było bardzo wysokie i wiele zawodniczek próbowało oderwać się od peletonu. Odskakiwać próbowały między innymi Elisabet Escursell Valero (Rio Miera – Meruelo – Cantabria Deporte), Marta Lach (Ceratizin-WNT Pro Cycling), Nicole Hanselmann (Burgos Alimenta Women) czy Laura Tomasi (Ale BTC Ljubljana), jednak wszystkie ataki szybko były neutralizowane.
Ostatecznie żadnym zawodniczkom nie udało się uformować odjazdu. Na podjeździe pod Alto de Las Hoyas z peletonu zaatakowały Cecilie Uttrup Ludwig (FDJ Nouvelle Aquitaine Futuroscope), Niamh Fisher-Black (SD Worx) i Pauliena Rooijakkers (Liv Racing), lecz zostały doścignięte chwilę po przejechaniu przez górską premię. 17 kilometrów przed metą od okrojonego peletonu odskoczyły Evita Muzic (FDJ Nouvelle Aquitaine Futuroscope) i Sabrina Stultiens (Liv Racing), lecz i one dość szybko zostały złapane.
Około 10 kilometrów przed metą kolejne zawodniczki próbowały swoich sił w atakach, lecz za każdym razem to duża grupa okazywała się silniejsza. Po chwili z peletonu zaatakowały Karol-Ann Canuel (SD Worx) i Elise Chabbey (Canyon//SRAM Racing), które wypracowały sobie kilkusekundową przewagę. Zostały jednak wchłonięte przez pędzącą grupę na ostatnim kilometrze.
O zwycięstwie zadecydował finisz z kilkunastoosobowej grupy, w którym najszybsza była Cecilie Uttrup Ludwig. Tuż za nią uplasowała się Katarzyna Niewiadoma (Canyon//SRAM Racing). Podium uzupełniła aktualna mistrzyni świata – Anna van der Breggen (SD Worx).
