Dusty Gravel - Lacs de l'Eau d'Heure

Historical weather data shows average highs of 55°F and lows of 39°F, with a 50% chance of rain on any given day, and gusts reaching 28 mph. "And this time the promised layer of dust was indeed present!" The 2025 edition delivered dry conditions requiring "maximum concentration" for "tight corners on a dry surface." Multiple riders suffered flats on the early gravel sections, suggesting surface conditions affecting equipment. More weather exposure than Belgian Waffle Ride San Diego.[4]

Start/finish at the Plate Taille dam at Lacs de l'Eau d'Heure with 9:00 AM (70km) and 9:30 AM (110km) start times. Part of the 3,000-rider Gran Fondo Belgium weekend provides shared infrastructure, though the Sunday Gran Fondo "completely fell apart after a massive crash shortly after the start."[6]

"The region around the Lacs de l'Eau d'Heure is not known for its gravel roads," yet organizers created routes with "beautiful sections through the forest." The course explores Belgium's largest lake system through hidden trails, though starting from established tourist infrastructure limits wilderness factor.[1]

Second round of the new Dusty Gravel Series launching in 2025 with zero racing history. While marketed for "all enthusiasts" seeking "performance or simply pleasure on two wheels," the series hasn't established credibility or notable winners in competitive gravel racing yet.[7]

If you're local to Belgium—yes, it's good value. If you're traveling—skip it.
