Recreational off-roading is popular among a sub-section of the owners of four wheel drive or all-terrain vehicles and motorcycles. There are numerous categories of off-roading, with something suitable for all levels of experience and equipment.
Some of the major categories of recreational off-roading are listed below.
Dune bashing
Driving over sand dunes.
Greenlaning
Greenlaning or two-tracking is one of the least extreme categories. It is generally suitable for any four wheel drive vehicle, even with factory tires and equipment. The term greenlane refers to the fact that the routes are predominantly along unpaved tracks, forest tracks, or older roadways that may have fallen into disuse.
Mudding
Mudding involves finding a large area of wet mud or clay and attempting to drive as far through it as possible without becoming stuck. Usually, the stock tires supplied with four by four vehicles are completely inadequate for this type of off-roading, and Mud-terrain tires are required. Strongly attached recovery points are also recommended to enable the vehicle to be towed out if it becomes bogged down.
Rock crawling
Rock crawling is a highly technical category of off-roading. Vehicles are typically modified with larger than stock tires, suspension components that allow greater axle articulation, and changes in the differential (mechanics) gear ratio in order to provide the ideal high torque/low speed operation for rock crawling to traverse obstacles.
Rock racing
Rock Racing is very similar to rock crawling in the fact that the vehicles are driven over rocks, the difference is that there are no penalties for hitting cones, backing up or winching as is done in rock crawling. Rock racing also involves a degree of high-speed racing not seen in typical rock crawling.
Formula off-road
Formula off-road is a high powered version of off-road competition. Vehicles are highly modified or specially built using sand drag tires and long travel suspension components that allow jumps and rough handling and long axle articulation, and a secure roll cage for the driver. Formula off-road cars often use highly tuned V8:s with superchargers or nitrous oxide injection systems.
Competitive Trials
Trials are probably the safest form of motorsport. All progress is made at low speed, and the emphasis is on skill rather than finishing first. However, trialing can be highly competitive.
Cross Country Vehicle trialing
The terrain covered will be of greater difficulty and will usually require more judicious use of speed to get the vehicle across certain obstacles, so the risk of vehicle damage is greater. Whilst no trial is intended to be vehicle-damaging, and a well-driven vehicle should be able to complete even the toughest CCV course without damage, mistakes and accidents are inevitable.
Punch & Winch challenge
This is the most recent and usually the most difficult, form of course trialing. A course is laid out with either a series of punches or gates and vehicles must collect as many punches as possible or complete as many gates in a course as possible. Winching is a definite skill in itself, aside from off-road driving, and brings elements of team-playing into the trial, as a successful (and safe) vehicle recovery needs at least 2 people to complete. A Winch Challenge may extend to other off-road driving skills, such as building a log bridge to cross a river.
