Mathieu van der Poel came out on top in his heavyweight showdown with arch-rival Wout Van Aert to claim a fifth cyclo-cross world championship on Sunday.
Van der Poel rated the triumph, on a track designed by his father Adrie, as "one of the top three moments of my career".

In a thrilling closing duel between the pair on this their 11th cyclo-cross meeting this season it was Van der Poel who held the ace card.
He sprinted clear of Van Aert 120 metres from the line to put a couple of bike lengths between him and his rival.
Van Aert's Belgian compatriot Eli Iserbyt took third, 12 seconds adrift.
Van der Poel said the key to his win was "remaining calm throughout the race".
"We both quickly realised that it was going to be possible to give the other the slip," he added.
Van Aert said he had been convinced "Mathieu was going to try something on before the sprint".
"I was so focused on that scenario I was a little taken aback when it didn't pan out like that," he explained, saying he should have tried sprinting for the line earlier "because you can do that on this circuit".
Van der Poel, the grandson of three-time Tour de France runner-up Raymond Polidor, was adding this to his previous title wins in 2015, 2019-2021.
