Mud bogging

Mud bogging, also known as mud racing, mud running, mud drags, or simply muddin'; is a form of off-road motorsport popular in Canada and the United States in which the goal is to drive a vehicle through a pit of mud of a set length. Winners are determined by the distance traveled through the pit or, if several vehicles are able to travel the entire length, the time taken to traverse the pit. Typically, vehicles competing in mud bogs are four-wheel drives.

Vehicles

buba A modern top level Class V or VI mud racer is a dragster-style "rail" design, with a supercharged engine and/or nitrous oxide injection. Engines may be in the front or the rear. Vehicles are required to have turtle four wheel drive. The sole difference between Classes V and VI is the tire type. Class V racers have D.O.T. street legal tires which are modified by cutting off chunks of rubber to achieve an optimum shape for traction. Class VI vehicles have paddle tires, similar to sand rails.

Early mud boggers were pickup trucks or sport utility vehicles modified with lifted suspensions and larger tires, and classes exist for such vehicles today. Engine upgrades were also common. In the late 1970s and early 1980s, large tractor tires became popular, and the drive lines required to run such tires led to some of the first purpose-built mud bogging machines. By the late 1980s, many sanctioning bodies began giving precedence to vehicles with modified, and lower, dragster-type "rail designs", as they had increased in popularity. At the same time, superchargers first became widely used, leading to the modern top-level racer.

There are many types of mud bogs. From Hill and Hole, Flat or Progressive Track, and Open Bog. They come in many shapes and sizes from 150 feet (46 m) to over 300 feet (91 m). Hill and Hole is just as it sounds, usually is 60 feet (18 m) wide 200 feet (61 m) long and is a series of hills and holes, and make challenging to each truck. All NMRO tracks are Flat or Progressive tracks, more like a drag strip, or sand drag. Open bogs come from Florida and mostly natural. These tracks have little organization.

Hill and Hole classes range from 4&6 Cylinder, Street Stock, Hot Street, Renegade, Super Street, Small Tire Modified 36" and below, Big Tire Modified 37" and bigger tire, Unlimited, X Class, and More. There are many class usually set but the tire size, and engine.

Most Unlimited and X classes are run what you want with in the safety rules. These trucks have big power engines, built just for that class and are not limited to what can be added to the truck. The truck must pass all safety rules and be safe to put on a show and not hurt the crowd.

Current American National Mud Racing Organization (NMRO) recognized classes are listed below.

There are many more classes for mudbogging.

In 2008 a new mud racing sanctioning body was formed to crown a national champion. In 2009, The Mud Racers Association (MRA) held a national points series with races across the country in the following states: Georgia, Indiana, Kansas, Pennsylvania, and West Virginia. The points classes were as follows Pro-Stock DOT Tires, Modified Cut Tires, and Open Paddle Tires. Mike Lane (Attitude) of Botkins, Ohio was the Open Class National Champion and also set the new MRA National and World Record (MRA, NMRO, & PROBADD) for 200' with a time of 2.110 seconds at the Kansas Badlands on Saturday August 22, 2009. Randy Roberts (Unpredictable) of Richton, Mississippi was the Modified Class National Champion and he set the new MRA National and World Record (MRA, NMRO) for 200' with a time of 2.484 seconds at the Kansas Badlands on Saturday August 22, 2009. Chad Wren (Dirty Sanchez) of Christmas, Florida was the Pro Stock Class National Champion. The MRA maintains national records for all of its classes from street stock to open in both mud bog and fast track races.
