In the lead up to the race, the barriers were earmarked as a place where Van der Poel could distance his rival. The course and its man-made elements were designed by Adrie van der Poel, a 1996 elite men's World Champion in 'cross and father of Mathieu. He added the boards on an uphill section close to the finish, and had them installed at the maximum height limit of 40 centemetres (16 inches), rather than the 35-centemetre height that is prevalent in other races during the regular season.
The deck was stacked against Darth van Aert! I wonder if they had the drone pilot in on it, too. 🤔🤡
What a rivalry and pair of class sportsmen.
The spring classics will be great. Again.
