At 53 kilometres from the finish, the peloton caught the early breakaway riders. The black and yellow formation worked hard and Coryn Labecki put Marianne in perfect position at the front of the group.
Several attacks followed. They were all unsuccessful, so at twenty kilometres from the finish the peloton was still complete. When Lotte Kopecky attacked, Vos followed with six other riders, including Demi Vollering and Elisa Longo Borghini. Together they rode towards Via Santa Caterina in Siena. Vos had to let go just a few kilometres from the finish, resulting in seventh place after 136 dusty kilometres.
“As a team, we rode a good race, but I would have liked to do better”, sighed a slightly disappointed Vos. “We worked together well, we were in front all the time and we never really got into trouble. I never felt unsafe. But in the final the pace was high and at the decisive moment I could not keep up anymore. I hoped I could recover and manage to come back, but it was not enough.”
