Second place went to Italy’s Marta Bastianelli.
Saturday’s race ran simultaneously with the men’s and was controversially stopped midway through after the women came close to catching up with the earlier race.
The next women’s race in the Spring Classics season is the Strade Bianche in Tuscany, Italy, which takes place on March 9.
