RIDERS REPORT
Gravel sections with marbles
Riders can lose wheels on the gravel when hitting the marbles, especially on slight banks where you can drift down and crash.
The course features gravel sections with marbles that can cause riders to lose traction and crash, particularly on banked sections where bikes can drift down.
Very sticky mud conditions that accumulate heavily on tires and make cycling extremely difficult.

Frequently Asked Questions

Historical weather data shows average highs of 64°F and lows of 47°F, with a 60% chance of rain on any given day, and gusts reaching 30 mph. May racing conditions in South Limburg allow for semi-slick tire recommendations in typical dry weather, supporting manageable racing for the international field of 2,550 participants. The Gemeentegrot cave section provides constant cool temperatures as a unique climate refuge during the race effort. Similar climate challenges to SBT GRVL.[11]

The race was "perfectly organized, a friendly atmosphere," while Sebastiaan highlights "the course was well marked and there were volunteers everywhere to ensure safety." The Shimano Experience Center provides proper facilities including changing rooms, showers, secure lockers, and barista coffee service for the 2,550 riders from 26 nations.[9]

"Don't expect endless straight gravel roads like in the Achterhoek or Drenthe. Here everything is shorter, steeper and more intense. Climbing, steering, biting down." The route passes through Château St. Gerlach Sculpture Park and marl cliffs from old quarries, providing civilized European exploration rather than wilderness adventure.[1]

Tim Wellens arrived "fresh off a 3rd place finish on the white gravel roads of Strade Bianche" and secured his UCI Gravel World Championships front row start with victory. Europe's largest one-day gravel event attracts WorldTour talent and cycling legends, though it's still establishing competitive identity in gravel's hierarchy.[11]

If you're in Netherlands/Europe and want a local event—yes, it's solid. If you're international—there are better options.
