Lars Boom attacked on the hard climb halfway the second lap and managed to create a serious gap by drilling himself through the 35-metre-long sand section just after the climb.

His main opponent Niels Albert followed on a fair distance and could only secure his silver medal, finishing 1:22 behind Boom.

Romain Villa followed 20 seconds behind Albert to take the bronze.
