In the evolving landscape of mountain bike trail construction, innovative techniques are emerging to supplant conventional bench-cut methods. These newer approaches prioritize enhanced durability, minimized upkeep, and a more dynamic riding experience. Central to this shift is the creation of elevated trail treads, a method that leverages specific soil types and strategic excavation to produce superior paths. This advancement promises not only a more engaging journey for cyclists but also a significant reduction in the environmental footprint and ongoing maintenance burdens, albeit with a potentially higher initial investment.
The Evolution of Trail Construction: From Bench Cuts to Elevated Treads
For many decades, the standard for creating mountain bike trails involved the bench-cut method, a technique that shaped a flat path directly into hillsides. However, as trail building technology and understanding of environmental impact have advanced, new, more sophisticated approaches are gaining traction. One such method involves constructing a slightly raised trail surface, moving beyond the traditional bench cut to improve both the longevity and the rider's experience. This elevated design is not merely a cosmetic change; it fundamentally alters how trails interact with their environment, particularly concerning water management. Trail builders are now focusing on creating paths that are not only more resilient but also more enjoyable, integrating natural features that amplify the terrain's characteristics.
This pioneering technique, championed by experts like Steve Wentz of Momentum Trail Concepts, involves a meticulous process. Rather than simply excavating directly into the ground, builders first remove the organic topsoil. They then dig a 'borrow pit' nearby to access superior mineral soil, especially effective with clay-rich varieties. This high-quality soil is then used to construct the elevated trail bed, allowing for the incorporation of undulations and other engaging features that enhance the riding experience. After the trail section is complete, the organic material initially removed is backfilled into the borrow pit, ensuring minimal environmental disturbance and leaving no visible traces of the excavation. This method ensures the trail blends seamlessly with its surroundings, offering riders an immersive and natural singletrack journey that appears as if it has always been there.
Advantages and Investment in Advanced Trail Building
The implementation of an elevated trail tread using high-quality mineral soil offers several distinct advantages over conventional construction methods. A primary benefit is the significantly improved water drainage. Unlike traditional bench cuts where water often accumulates, an elevated tread allows for bidirectional drainage, shedding water to both sides of the path. This design feature is crucial for preventing erosion and maintaining the integrity of the trail surface, particularly in diverse climatic conditions. Steve Wentz emphasizes that this approach ensures water is absorbed more naturally into root systems, allowing for greater design freedom regarding trail gradients and curves, without the constant concern of directional water runoff. This results in a trail that is not only more stable but also requires substantially less ongoing maintenance, a critical factor for long-term sustainability.
While the initial cost of constructing elevated trails can be 50% to 100% higher than traditional methods, due to the increased time and specialized techniques involved, experts agree that the long-term benefits far outweigh this investment. Curtis Johnson of the Biggest Little Trail Stewardship highlights that the enhanced durability and reduced maintenance needs translate into significant savings over time. The construction process itself is also more efficient, requiring less hand-finishing work by volunteer crews. With an excavator, a skilled builder can complete sections with minimal follow-up, leaving a pristine trail that requires no backslope cleanup. This innovative approach ensures that the substantial upfront investment in superior construction leads to a more resilient, environmentally sound, and ultimately more cost-effective trail system, addressing the common challenge of securing funding for ongoing trail upkeep rather than just initial builds.
