If you like hurtling through the streets, flat on your back and travelling at break-neck speeds, then perhaps you may be interested in street luge - or professional help.
Street luge was an invention of Southern California. The founders of the sport were originally skateboarders, who pondered whether they might not achieve a higher velocity by lying down on their skateboards. This suspicion was confirmed, with riders now reaching speeds of up to 64kph.
From these auspicious beginnings in the 1970s, professional bodies have emerged. After twenty years on the fringes street luge was to become the symbol of an extreme sport counter-culture that captivated audiences and led to substantial media coverage.
Sydney Street Luge is Sydney's first street luge club, with the governing aim of making the sport more affordable and accessible.
They achieve this aim by hosting events, including "Freeride" and "Funday". They also run certain beginner's days in order to attract new converts to the street luge cause.
They also dedicate a considerable amount of time promoting the vital gear that protects the safety of participants.
Another significant aspect of the club's work is to promote the involvement of women in the dangerous sport: offering support to the so-called "Ladies of Luge".
As street luge becomes a bigger phenomenon among adrenaline junkies, it has become a palpable presence in the forums of organisations traditionally concerned with more conventional "gravity sports". With the official endorsement of the Australian Skateboard Racing Association, there is no doubt that street luge will continue to develop and thrive in Sydney.
