At the opposite straight of the finishing line, there is a crossing area, where the skaters must change lane.[3] The design and dimensions of a speed skating track have remained more or less unchanged since the foundation of ISU in 1892.[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 few are suitable also for bandy, like Hamar Olympic Hall,[7] Ice Palace Krylatskoye,[8] and Medeu.[12] In Norway there is an agreement in place, stating that an indoor arena intended primarily for either bandy or long track speed skating, shall have ice surface for the other sport as well.
