CHOOSING A ROUTE
Read the colour. Then the ground.
The definitions below follow Forestry England’s current national grading guidance. A grade is still a general indication, not a promise that every trail or operator uses identical terrain.
Green · easy
Usually wide, low-gradient and relatively smooth, with gentle climbs, descents and avoidable features. It is not automatically traffic-free or hazard-free.
Blue · moderate
Moderate climbs and descents, variable surfaces and technical features such as roots, rock steps, berms and rollable jumps.
Red · difficult
Steeper climbs or descents with larger jumps, berms, roots, drop-offs, rocks and rapidly changing surfaces. Confident off-road skills, braking and line choice are important.
Black · severe
Long or steep climbs and descents, jumps, drop-offs, sharp corners and difficult features. Commitment and advanced bike control are required.

Other labels
Orange, downhill, freeride, pro-line and double-black systems are operator-specific and may include mandatory jumps or drops. Natural or “ungraded” does not mean easy: navigation, remoteness and changing ground conditions add risk.
Should I ride it?
- Read the operator's current description and inspect trailhead signs.
- Start one level below your limit at an unfamiliar venue.
- Ask whether features have ride-around lines and whether climbing fitness is required.
- Turn back or walk a section if conditions or confidence change.
