How we define Trail, Technical and Advanced terrain for MTB courses.
for the Trail Mountain Bike Leader Award
Trail terrain is non-technical. This means that it does not involve specific route selection (for example between rocks, roots or other obstacles) in order to ride on it. It can be as narrow as handlebar width. Typical trail terrain includes: forest tracks, fireroads, cycleways, and other smooth ground. Public highways and roads also fall within trail terrain.
