In the finals, Lindsey Jacobellis lead from the start, but was passed first by Moioli, and then by Pereira de Sousa Mabileau. Before the final jump, she was fifth, also behind Samková and Chloé Trespeuch, the 2014 bronze medalist. In this jump, Trespeuch fell and crossed the finish line on her back; this allowed Jacobellis to finish fourth, 0.03 seconds behind Samková. Trespeuch, despite her fall, was fifth, and the last finalist, Aleksandra Zhekova, sixth. Jacobellis was consistently rated favorite in this Olympic event since 2006 and only won a medal once, silver in 2006.[3]
