==Quad speed skating==
Quad roller-skating racing is the precursor to the popularity and acclaim received by competitive racing on in-line skates.  Up until 1991, all World Championships were held on quad skates. Most events at the 1992 World Championships were specific to quads, however, some events were classed as "open" giving the athlete the option of choosing either quads or in-lines.  The same criteria were applied for the 1993 World Championships. In 1994 all events were declared as "open".  Despite this, it had soon become evident that in-lines were predominantly quicker than quads on all surfaces and all tracks and to this end athletes opted for in-lines over quads, as is still the case today.
