The finale of the 89km race was marred by crashes but Hosking escaped unscathed finishing the sprint ahead of Lotta Lepistö (Cervelo-Bigla) and former winner Marianne Vos (Rabo-Liv) in third.
The 12th round of the Women's WorldTour offered the field a high-speed circuit race along the famed city blocks of Paris, looping around the Arc de Triomphe and Place de la Concorde. It was a deceptively hard 13-lap race, held on a 7km course mixed of flat sections, uphill drags and cobbles that make it a tough one-day event.
