The World Road Cycling Championships began on Thursday in Imola, Italy in a dramatic way.

Anna van der Breggen, 30, drove to win the women’s time trial.

The Belgian World Cup gold was decided by the reigning champion, the fierce expulsion of Chloe Dygert from the USA.

The BBC writes that 23-year-old Dygert led the 31.7-kilometer race clearly, 26 seconds apart, to Breggen, before his fall.

In a sharp bend curving to the right, Dygert lost control of his bike.

A video of the crash can be seen below.

The Cyclingnews website reports that Dygert was transported by helicopter to Bologna for treatment.

- Dygert was on his way to his second world championship when he had to be suspended after falling and flying over a guardrail.

All we know is that he is conscious and able to speak.

More updates are coming, the U.S. Cycling Union said, according to Cyclingnews.

Social media estimated that the race’s pre-favorite got the worst injuries to its lower limbs.

- I just saw pictures of Chloe Dygert's injuries after her crash.

His left knee looks really bad, hoping for a full recovery, wrote on Twitter including journalist Vince Van Genechten.

In addition to road cycling, Dygert has also been successful in track cycling.

At the 2016 Rio Summer Olympics, Dygert was winning silver in the U.S. team in the track cycling chase race.
