Rogue trails are everywhere: hidden behind neighborhoods, winding through forest hillsides, and quietly passed from rider to rider. But what’s the cost? This article explores the world of unsanctioned trail building—why they exist, who builds them, the risks to access and ecosystems, and how we might bridge the gap between rebellion and responsibility.

I recently caught up with the president of a non-profit trail stewardship organization as we talked about their plans for the upcoming year. One of their goals? Work to officially adopt a beloved unsanctioned trail system that is on federal land. When he first shared that with me, my first thought was not only about this interview series with rogue trail builders but also about why and how conversations like this may encourage more unsanctioned trails. Why?

Unsanctioned trails. Those two words combined can cause a firestorm of emotion, debate, and consternation. That’s why I am launching a new series to explore this topic …

Why explore this topic? Some argue that unsanctioned trails represent a shady and dubious past from which we’re finally breaking away. For some, there’s a level of shame to talk about what took place “back then.” While that is the origin story of mountain biking, many are quick to push it aside and talk about how or why we’ve moved on. Yet, others are tired of the bureaucracy and tortoise-like pace of building “legal” trails. I told you this is a controversial conversation. However, we need to have these difficult conversations.
