Street luge is an extreme gravity-powered activity that involves riding a street luge board (sometimes referred to as a sled) down a paved road or course. Street luge is also known as land luge or road luge. Like skateboarding, street luge is often done for sport and for recreation.
Other than the supine riding position and very high speeds (70–102 mph / 112–164 km/h), street luge has little relation to its winter namesake (luge).
Street luge was born in Southern California as downhill skateboarders found they could reach faster speeds by lying down on their skateboards. This early form of the sport is now referred to as "laydown skateboarding".
In 1975, the first professional race was held at Signal Hill, California, and hosted by the U.S. Skateboard Association. The race winner was based on top speed. The boards used in this race varied from basic skateboards to complex skate cars in which the rider was completely enclosed by plastic or fiberglass. The sport was not commonly referred to as street luge at this time but the term luge was used to describe some participants' riding position. Most contestants were standing up; however, an opening in the rules enabled riders to choose their own board position, including supine. By 1978, repeated injuries to both riders and spectators halted the races at Signal Hill.
Roger Hickey and Don Baumea from the Signal Hill races kept the sport alive by continuing to hold races in Southern California. Around the early 1990s, both underground and professional races continued to be held in Southern California by such organizations as the Underground Racers Association (URA), Federation of International Gravity Racing (FIGR) and Road Racers Association for International Luge (RAIL). Race organizers in the 1980s and 1990s started implementing many more equipment, safety and race regulations.
Meanwhile, in the early 1990s, some Austrian skateboarders started sitting down on their skateboards on the way back from teaching skiing in the Alps. This activity lead to a classic style street luge race in the Kaunertal Valley, in western Austria, called Hot Heels. At the outset, the founders started lying down on wooden boards closer to large skateboards than the usual street luge, and with smaller wheels: this came to be known as classic luge, or buttboard. The race, which ran until 2003, came to function as a de facto world championships, including all the downhill disciplines such as street luge, stand up downhill skateboard, classic luge, gravity biking and inline skating. There is now a healthy street luge riding and racing presence in many European countries (see below).
