Mountain biking trail grades
Mountain biking is a potentially hazardous activity carrying a significant risk. It should only be undertaken with a full understanding of all inherent risks. These trail grades are guidelines that must always be used in conjunction with the exercise of your own experience, intuition and careful judgment.
|Grade||Trail and surface types||Gradients and technical trail features||Skills needed|
|G.1 Easy||Relatively flat, wide and firm surfaces. Trail surface might be loose, uneven or muddy at times, Might include short flowing single track-style sections.||Climbs and descents are mostly shallow. No challenging features.||Basic bike skills are required for this grade. It is suitable for beginners or novice cyclists or for most people in good health|
|G2 Intermediate||As for ''easy", plus specially constructed single track trails. Trail surface might include small obstacles of root and rock.||Most gradients are moderate but might include short steep sections. Includes small technical trail features (such as roots and rock).||Basic off-road riding skills to cope with uneven surfaces and small obstacles. Suitable for intermediate cyclists or mountain bikers with basic off-road riding skills. A good standard of fitness can help.|
|G3 Difficult||Steeper and tougher, mostly single track with technical sections. Expect very variable surface types.||A wide range of climbs and descents of a challenging nature will be present. Expect boardwalks, large rocks, medium steps, drop-offs, cambers and water crossings.||Good off-road skills and techniques to cope with technical trail features. Suitable for proficient mountain bikers with good off-road skills. A higher level of fitness and stamina is required.|
|G4 Severe||As for " difficult", but with an expectation of greater challenge and continuous difficulty. Can include any useable trail and might include exposed open hill sections.||Expect large, committing and unavoidable technical trail features. Sections will be challenging and variable. Might also have 'downhill' style sections.||Advanced level off-road skills and technical ability. Suitable for expert mountain bike users, used to physically demanding routes. Suitable for very active people used to prolonged effort.|
|G5 Extreme:||Severe constructed trails and/or natural features. All sections will be challenging. Includes extreme levels of exposure or risk. Jumping ability obligatory.||Will include a range of small, medium and large technical trail features, including downhill trails, free ride sections and mandatory jumps.||A good standard of fitness is recommended but technical skills are more important.|
