The rink
A standard long track speed skating track is, according to the regulations of the International Skating Union (ISU), a double-laned track with two curved ends each of 180°, in which the radius of the inner curve is not less than 25 metres and not more than 26 metres. The width of the competition lanes is 4 metres. At the opposite straight of the finishing line, there is a crossing area, where the skaters must change lane.[1]
At international competitions, the track must be 400 metres long, with a warm-up lane at least 4 metres wide inside the competition lanes.[2] For Olympic competitions, the track must also be enclosed within a building.[3]
The design and dimensions of a speed skating track have remained more or less unchanged since the foundation of ISU in 1892.
The speed skating track is also used for the sports of Icetrack cycling and Ice speedway
Measurement and demarcation
The measurement of the track is made half a meter into the lane.[4] The total length of the track is the distance a competitor skates each lap, i.e. the length of two straights, one inner curve and one outer curve, in addition to the extra distance skated when changing lanes in the cross-over area, which on a standard track equals 7 centimeters.
- A 400 m track with inner radius 25.0 m has 113.57 m long straights
- A 400 m track with inner radius 25.5 m has 112.00 m long straights
- A 400 m track with inner radius 26.0 m has 110.43 m long straights
The demarcation of the competition lanes are made by painted lines in the ice (or a set of painted marks) and movable blocks of rubber. On outdoor tracks, snow may also be used for demarcation of the competition lanes.[5]
Alternative speed skating tracks
Although ISU regulations state that minimum measures for a standard speed skating track, alternative track lengths may be used for competition. The minimum requirements are track length on 200 meters, radius of inner curve of 15 meters and width of the competition lanes 2 meters.[6]
Short track speed skating tracks have a length of 111.111 metres (364.54 ft). The rink is 60 metres (200 ft) long by 30 metres (98 ft) wide, which is the same size as an international-sized ice hockey rink.
