Austria's Daniel Federspiel and Swiss rider Linda Indergand ruled the roost on the opening day of the Union Cycliste Internationale (UCI) Mountain Bike and Trials World Championships in Andorra.
They came out on top in the Cross Country Eliminator (XCE) event in Vallnord on a fast course which offered much for both competitors and spectators.
The format sees four riders race against each other with the top two progressing, and in the men's competition 2014 world champion Fabrice Mels of Belgium succumbed in the semi-finals.
Federspiel led the final from start to finish to take gold and the rainbow jersey, seeing off the challenge of 19-year-old New Zealander Samuel Gaze who took silver ahead of Germany's Simon Gegenheimer who took bronze.
Frenchman Kevin Miquel was the unfortunate fourth rider to finish outside of the medals.
Indergand was joined by two compatriots in the women's final, with Kathrin Stirnemann and Ramona Forchini lining up alongside Norwegian Ingrid Boe Jacobsen.
The eventual champion led from the start and opened up a 15 metre gap at one stage as she took the line with room to spare.
Boe Jacobsen took the silver medal to deny Switzerland a podium sweep, with Stirnemann, the 2014 champion, third.
Meanwhile, the Trials National Teams Competition was also contested with France clinching the gold medal.
Each country selected five riders to navigate five different obstacles on the course, with the French quintet of Vincent Hermance, Nicolas Fleury, Benjamin Durville, Manon Basseville and Nicolas Vallee racking up a score of 680 points for gold.
Switzerland took silver and Germany the bronze.
The Championships continue tomorrow with the Cross Country Team Relay event and the quarter finals of the trials for the elite women.
