The event served as the final qualification competition for the Tokyo 2020 mountain bike event, with riders seeking to earn points to boost their nation’s ranking.

Pidcock was among the riders requiring a strong result as Britain went into the World Cup outside the Olympic quota places.

The 21-year-old attacked on the third of six laps and pulled away from Dutch star Mathieu van der Poel.

Pidcock, riding for Ineos Grenadiers, surged clear to secure victory in a time of 1 hour 20min and 55sec.

His maiden win at senior World Cup level was the first by a male British rider since 1994.

The under-23 world champion finished with a one-minute cushion over Van der Poel.

Switzerland’s Mathias Flückiger completed the podium places, ending a further 15 seconds back.

The result should be enough for Pidcock to have earned Britain a quota place for Tokyo 2020, with the updated rankings expected to be published later this week.

The top two nations in the rankings with be able to field three riders at Tokyo 2020, with countries ranked third to seven having two spots.

One quota place will be granted to countries ranked eighth to 21.

Three places have already been granted to athletes at Continental Championships, with a further four awarded at World Championships and one nation quota for Japan.

France’s Loana Lecomte underlined her status as a potential contender for the women’s Olympic title after winning her second consecutive World Cup race.

Lecomte topped the podium at Albstadt last week and repeated the feat with a dominant performance in the Czech Republic.

The under-23 world champion attacked on the first climb to open a gap to her rivals before crossing the line in a winning time of 1:25:13.

American Haley Batten finished 1:39 down as the runner-up, with Australia’s Rebecca Mcconnell crossing a further 12 seconds adrift to complete the podium places.

Leogang in Austria and Les Gets in France are due to host cross-country World Cup events prior to the Olympic Games, but both fall outside the qualification window.
