Long track is 400 metres; short track packs chaos into 111
Speed skating races timed distances on ice in three main families: long-track, short-track and marathon. The International Skating Union, founded in 1892 as the first winter-sport federation, still distinguishes Olympic "speed skating" on 400 m ovals from "short track" on hockey-rink loops.
Long-track skating, the older Olympic form, usually uses a standardized 400-metre ice oval (sometimes 200, 250 or 333⅓ m). Short-track racing runs a 111.12 m oval inside a hockey-sized rink; the longest Olympic individual distance is 1,500 m, with women's relays at 3,000 m and men's at 5,000 m, often decided by knockout heats of four or five. Falls and disqualifications are common. Dutch marathons may roam natural canals and lakes or simply lap a 400 m artificial track a hundred times.
Bone skates for winter travel appear over a millennium ago in Scandinavia and the Netherlands. Norway's King Eystein Magnusson boasted of skating skills in medieval sources, and a Scotsman fitted iron blades in 1592—hardware that helped the pastime spread. Today the sport thrives especially in the Netherlands, Norway and South Korea, with World Cup stops across North America, Europe and Asia, including two events at Thialf in Heerenveen.
Rules differ by format. Long-track pairs racing punishes almost any interference with a lane-mate, though a skater who cannot hold the inner curve may shift outward late if clear. Mass starts tolerate more contact. Elite long-track team racing centres on the team pursuit; short-track and inline relays allow exchanges almost anytime except late laps. Inline ovals stretch 125–400 m (banked tracks max 250 m), with road loops and point-to-point courses adding still more geometry.
Across formats the shared craft is converting thin steel edges and crouched aerodynamics into sustained speed—whether alone against the clock on a four-hundred-metre ribbon or jostling through a short-track pack.
