Artistic roller skating (sometimes called roller figure skating) is a group of roller skating events similar to figure skating on ice. Skaters may use either quad or inline skates, although quad and inline are separate events, and do not compete together. Artistic skating on inline skates is quite rare, as quads are better able to hold edges and perform tight spins. Read more.

A game consists of three periods of twenty minutes each, the clock running only when the puck is in play. In international play, the teams change ends for the second period, again for the third period, and again after ten minutes of the third period. In many North American leagues, including the NHL, the last change is omitted.

Inline speed skating races are held in a variety of formats and on a variety of surfaces. Indoor races are held at roller skating rinks on coated wood floors and are common primarily in the United States, which has a long tradition of roller skate racing at rinks. Tracks are about 100 m in circumference. Read more about different race formats.

The technique for inline speed skating is generally the same as the classic ice speed skating style. Tactics in outdoor inline racing are similar to those of marathon ice speed skating and of road bicycle racing. Read more.
