Champions Laura Smulders and Niek Kimmann won the final International Cycling Union (UCI) BMX Supercross World Cup races of the season in Santiago Del Estero, Argentina.

Both Dutch riders had already sealed the individual titles before the last race of 2019 today, with Smulders wrapping things up with victory yesterday on the same course.

Kimmann claimed the men's crown at the previous event in Rock Hill, United States.

They each ended their World Cup campaigns on a high note, while also ensuring The Netherlands finished top of the nations rankings for both men and women.

Smulders won the women's race in a time of 33.463sec, in front of Russia's Natalia Afremova in 34.250 in second place and Felicia Stancil of the US who was third in 34.331.

It means Smulders finishes the season on 2,225 points, in front of American Alise Willoughby – who did not race in Argentina – on 1,800.

Stancil's third was enough to put her in the overall bronze medal spot with 1,640.
