Ice racing is a form of racing that usescars,motorcycles,snowmobiles,all-terrain vehicles, or other motorized vehicles. Ice racing takes place on frozen lakes or rivers, or on groomed frozen lots. As cold weather is a requirement for natural ice, it is usually found at higher latitudes in Canada, the northern United States, and in northern Europe, although limited indoor events are held in warmer climates, typically on ice hockey rinks (motorcycles and ATVs only).[1] Tracks in North America vary from 1/4 mile to several mile-long (~400 m to several kilometer-long)[2] circuits.
Tracks used for ice racing include ovals androad courses.[3] Some tracks aredirt track racing tracks with the snow plowed off them. When there is no natural snow, an icy surface may be created by spraying the dirt surface with water when the temperature is below freezing. Artificial ice tracks (usuallyspeed skating ovals) are used where it is not possible to construct natural ice tracks. Some tracks are made by plowing the snow off an area of a frozen lake. Spectators frequently park their cars around the outside of the track on a frozen lake.[4]
In the UK, ice meetings have been staged at ice rinks. The longest running event, atTelford, features riders using conventional machines with spiked tires. In the late 1960s ice racing was staged at a number of rinks in Scotland and the machines used were rally-based machines with all season tires.
Ice racingtires are either studded or non-studded.[3] Studded tires have a stud such as a screw or bolt to provide better traction and increase speed.[4] Some studs are sharpened to increase penetration.[4] Tires cannot be purchased with studs, so the pit crews need to attach the studs to the tires.[4] Through 2008,Menard's Racing in Wisconsin manufactured and sold studded racing tires for cars, and they were required in many ice-racing classes. Cars with studded tires are generally required to containroll cages and increased safety equipment since they achieve much more speed with the greater cornering abilities.[3]
The sanctioning body's rule book generally specifies the length and type of stud, often with the goal of controlling the level of damage done to the ice surface. Aggressive studs can cause enough damage to be a safety concern as they wear through the ice on successive laps, particularly during door-to-door auto racing.
Non-studded tires are standard production snow tires, as used on highway-use passenger cars in colder climates. Drivers often usewinter tires.[3] Favorites among ice-racers include Bridgestone Blizzaks and Nokian Hakkapeliittas.
Ice racing includes amotorcycle class which is the equivalent ofSpeedway on ice. Bikes raceanti-clockwise around oval tracks between 260 m (0.16 mi) and 425 m (0.264 mi) in length. The race structure and scoring is similar to Speedway.
The bikes bear a passing resemblance to those used for speedway, but have a longerwheelbase and a more rigid frame. The sport is divided into classes for full-rubber andstuddedtires. The studded tire category involves competitors riding on bikes with spikes up to 30 millimetres (1.2 in) in length screwed into each tread-less tyre, each bike has 90 spikes on the front tyre and 200–500 on the rear. The use of these spikes in this discipline necessitate the addition of special protective guards (similar tomudguards) over the wheels which extend almost to the ice surface. The spiked tyres produce a tremendous amount oftraction and this means two-speed gearboxes are also required. As with speedway, the bikes do not have brakes. Czech made4-strokeJawa motorcycles have been the dominant force in this sport.
In the studded tyre class there is no broadsiding around the bends due to the grip produced by the spikes digging into the ice. Instead, riders lean their bikes into the bends at an angle where the handlebars just skim the track surface. Speeds approach 80 mph (130 km/h) on the straights, and 60 mph (97 km/h) on the bends. The safety barrier usually consists of straw bales or banked-up snow and ice around the outer edge of the track.
The riding style required for studded ice racing is different from that used in the othertrack racing disciplines. This means riders from this discipline rarely participate in Speedway or its other variants and vice versa.
The majority ofFédération Internationale de Motocyclisme sanctioned team and individual meetings are held inRussia,Sweden andFinland, but events are also held in theCzech Republic,Germany,Hungary (since 2000), theNetherlands, and occasionally other countries. Countries that dominated and won the majority of titles inIndividual Ice Racing World Championship (held since 1966) andTeam Ice Racing World Championship (held since 1979) were theUSSR and since 1991—Russia.[5]Canada's national touring series is sanctioned by theCanadian Motorcycle Association.
Automobile ice races have been most successful inFrance, where theTrophée Andros series, sponsored by an industrialjam (fruit preserver) manufacturer attracts ex-F1 drivers likeAlain Prost orOlivier Panis, manufacturer-backed entries of sophisticated4WD cars and internationaltelevision coverage. The Trophée Andros races mainly use damped snow (that is not very different from ice regarding car handling) tracks in French ski resorts with a final race on artificial ice in ParisStade de France. The 2006 trophy includes one round inAndorra. On several occasions a round also took place inCanada, in the Canadian Challenge, which is held yearly and is the most notable Ice Racing event in North America.
In the 1960s and 1970s, there were two major Ice Racing Championships, theNorth American Ice Racing Championship and theEuropean Ice Racing Championship. The North American was held inAnchorage, Alaska and their champions includeEarl Bennett andChuck Higgins, while MexicanFormula One driverPedro Rodríguez won his class and an exhibition race in 1970, and was 2nd overall.
Elsewhere, ice racing has proven to be a largelyrecreational pastime. There is no professional ice-racing sanctioning body in North America,[3] but there are clubs in several Canadian provinces (Alberta, Ontario, Manitoba, Quebec, Saskatchewan) and American states (New York, Michigan, Maine, Wisconsin, Minnesota, Alaska[6]). Some amateur and professionaldirt track and paved track racers use ice racing to hone their skills or to practice for the summer season.[3][4] Drivers often find that developing the car control skills needed on ice substantially improves their performance on a wet race track.
There is a new class in Canada called SS (street studs) where a car can run with the same modifications as a rubber to ice class, without the need for a roll bar.[7] This same SS classing, although referred to as Super Stud or Studded class, by some American Clubs (such as the Anchorage Alaska Sports Car Lions Club) require any car running studded tires to meet at least IT rules and requires a roll cage and full safety gear.[8] Some clubs even encourage people to ice-race their daily driver, and have strict no-contact rules to allow that safely.[9]
InRussia there is arally raid event, called theNorthern Forest run on ice and snow in the last days of February in the outskirts of the city ofSt Petersburg. Also, in Russia there is popular winter track racing, where pilots race on short ice oval track, usually hippodromes, covered with ice during winter.[10]
Conventionalrallying also takes place on ice. Most notably, the tarmac of theMonte Carlo Rally is occasionally covered with snow and ice. TheSno*Drift rally in Michigan is another example of such events.
There are many classes of racing vehicles. The racing vehicles are frequently divided into studded or non-studded tire classes. Nearly alldirt track racing vehicles could be raced on ice. Flying snow and ice powder limits visibility, so some vehicles are required to have a bright light, normally red or yellow, on the back of the car for greater visibility in the powder.[3][4]
Non-studded cars are selected by their weight since non-studded cars cannot carry high speed through a corner and cars cannot get much power to the slippery surface.[3] Lightweight front-wheel drive cars are generally the quickest.[3]
Ice racing was featured in the 1969James Bond filmOn Her Majesty's Secret Service withGeorge Lazenby andDiana Rigg as they attempted to evade their pursuers. The track was inSwitzerland.[3]
Motorcycle ice racing footage can be seen in theBruce Brown documentaryOn Any Sunday.
