Marianne Vos won the first cyclocross world cup of the season on Sunday.

The Brabant woman stayed ahead of her compatriots Lucinda Brand (second) and Denise Betsema (third) in an exciting battle in the American Waterloo.

The competition in Iowa was dominated by the Dutch women.

In the first rounds, the 34-year-old Vos was in the lead together with four compatriots and then Brand was alone in the lead for a long time.

Vos rejoined Brand in the final round and in the final the two were again joined by Betsema.

In the last corner Vos outsmarted her two competitors and then she sprinted to her first cyclo-cross victory since early 2019. Then she triumphed in Pontchâteau in France and also secured the overall victory in the World Cup a week later.

Last week Vos was still active in Paris-Roubaix.

There she finished second at an appropriate distance from the British Elizabeth Deignan.

Behind the Dutch trio in Waterloo, the Swiss Jolanda Neff finished fourth.

Annemarie Worst crossed the finish line in fifth place.

Puck Pieterse (eighth) and Yara Kastelijn (ninth) also finished in the top ten.

Van der Poel and Van Aert not in action with men

Later in the day, the men come into action in Waterloo.

Mathieu van der Poel and Wout van Aert are not at the start.

The next two cyclocross world cup competitions will also be held in the United States.

On Wednesday the riders will take action in Fayetteville and next Sunday in Iowa City.
