Activity levels and Helemet Warranty Guide
Mountain biking trail grades
Trail grades are split between those for cross-country singletrack trails and those for extreme trails and forest roads.
Understanding trail grades
Forest roads can be of variable difficulty and are therefore not part of a progression on to green and blue level singletrack trails. Similarly, orange-graded trails/features are not simply a progression on from singletrack grades. Explanations for each of the grading’s are given below the symbol tables.
