Right Trail in the Right Place: DIRTT “Build Levels” Explained

According to the recent DIRTT European Trail Building Sector Survey, 80% of European trail builders have worked on flow trails within the past two years. While the high demand for these trails is attracting more people to mountain biking, relying on just one type of trail won’t satisfy all riders or keep newcomers engaged as they progress in their mountain biking journey. In the world of mountain biking, one size definitely doesn’t fit all. 

Sustainability is central to DIRTT’s mission, and promoting the “right trail in the right place” is crucial. Sustainable trail building goes beyond minimising environmental impact; it involves creating trails that are socially beneficial and economically viable over the long term. By choosing trail types and construction methods suited to specific environments and community needs, we can foster positive relationships between riders and nature.

To address the varied needs of the trail community across Europe, DIRTT has developed resources around four different build levels: Rake-and-Ride, Hand Built, Machine Built, and Engineered. These levels represent a spectrum of trail-building techniques, each varying in intensity and complexity. By establishing these build levels, we aim to create a shared language, broaden understanding, and enhance legitimacy around the diverse methods used in trail construction. This approach contributes to more nuanced decision-making and planning processes regarding the “right trail in the right place.”

As a general rule, more intensive build levels suit developed areas where they can support higher user volumes and economic benefits without significant environmental impact. In contrast, less developed or protected areas require minimal impact, making manual techniques more suitable. Below are the key characteristics of each technique. While presented as different methods here, in real-life trail building situations, several techniques will often overlap and be used side by side.

Rake-and-Ride

  • Quick implementation: Trails are created by clearing organic material without significant alteration to the terrain. Ideal for rapidly establishing new routes with basic tools and “riding in” the trail.
  • Natural experience: Offers riders a natural, unrefined trail that will mature over time.
  • Limited capacity: Not suitable for large numbers of users.

Hand Built

  • Manual construction: Built entirely with hand tools, allowing for a rugged and natural riding experience.
  • Environmental sensitivity: Minimises impact on the surrounding ecosystem by avoiding heavy machinery.
  • Higher durability: More tolerable to higher user volumes compared to rake-and-ride trails.
  • Advanced features: Can involve more advanced methods like rock armoring and technical trail features.

Machine Built

  • Efficiency and scale: Uses machinery to construct trails more efficiently and handle larger projects.
  • Consistent quality: Machines can create uniform trail surfaces and larger features like berms and jumps.
  • Accessibility: Ideal for building trails that cater to a wide range of skill levels.
  • Resource intensive: Requires access to equipment, trained operators, and more advanced health and safety planning.
  • Environmental considerations: Needs careful planning to mitigate disturbances to the terrain and habitat.

Engineered

  • Large-scale projects: Involving multiple machines, large crews, and material import, typical in highly developed areas like bike parks.
  • Comprehensive planning: Requires detailed planning and coordination among planners, designers, and build crews.
  • Robust design: Focuses on long-term sustainability with designs that can withstand heavy use and challenging environmental conditions.
  • Regulatory compliance: Must meet strict standards and regulations, ensuring safety and requiring professional maintenance crews.
