Hammerstone owes its name to the rich presence of flint in the Valkenburg region, alongside the well-known marl. This Limburg mountain bike icon is all about rugged trails, technical challenges and a pure off-road experience.
In and around Valkenburg, you come together with fellow mountain bike enthusiasts for a weekend where sport, nature and a passion for mountain biking take centre stage. The programme offers plenty of room for different disciplines within the mountain bike sport.
Throughout the weekend, you enjoy challenging routes, great stories and a relaxed yet sporty atmosphere. It’s exactly this combination that made Hammerstone 2025 an edition many mountain bikers look back on with pleasure.
What truly sets Hammerstone apart are the carefully designed routes through the Zuid-Limburgse Heuvelland and the Voerstreek. These routes demand focus and respect — for the course itself, but also for other road users and for the environment in which the event takes place.
Hammerstone is more than just cycling. It’s a weekend where meeting, experiencing and enjoying come together. Around the start and finish area, you’ll find space for support, connection and socialising, allowing you to fully focus on your ride and the complete experience around it.
