Indoor Speed Skating
Indoor skating, a variation characteristic of competition in the United States, uses a 100-meter oval track in individual and relay events.
Outdoor Speed Skating
Outdoor speed skating, the recognized international standard, is categorized into road and track racing.
Road race courses usually take the form of an irregular closed loop with no bank on either side, or an actual stretch of closed road.
Track races, however, are on a closed, oval course usually measuring 200 meters and featuring banked sides.
