The women's cycling road race course featured a grueling climb and a treacherous descent over the final 20 kilometers in rainy conditions - and the Dutch rider leading the race at the time suffered a horrifying crash that allowed her compatriot Anna van der Breggen to win the gold medal.
Rain made the descent even tougher than it was yesterday - multiple male riders were involved in hard crashes - and time trial champion Annemiek van Vleuten was in golden position until she lost control around a bend and flipped foward. She appeared to land on her face.
The Royal Dutch Cycling Union confirmed in a tweet that van Vleuten "appears to be okay," and race commentators later said that van Vleuten is conscious and has been transported to a hospital.
The lead went to American Mara Abbott, but she was caught by a three-woman chase in the final 100 meters. Absolutely spent, Abbott was unable to beat van der Breggen and fell off the podium entirely, finishing fourth.
