Input: by Jerry Search, Southern California Speed Skating Association. From an article originally appearing in The Racing Blade, November 1994: For many years I have heard various statements of the actual speed in miles per hour (MPH) that speed skaters skate, anywhere from 20 to 40 MPH. Long Track Speedskating Preview The U.S. and long track speedskating are synonymous. Boasting 67 Olympic medals, including 29 golds, Team USA is traditionally poised to reach the medal stand each Olympic Winter Games due to the team's historic success. And remember that the stop-and-go tactics of pack-style skating also influence times, and true speed. Therefore... If you have the opportunity to have timed flying 1-laps, then this would be your fastest true speed (although you could probably skate a little faster in a long track straight-away sprint of maybe 100 meters). The Olympic long track competition will be held at the Gangneung Oval, which is situated next to the short track speedskating venue in the coastal city of Gangneung. The venue seats up to 8,000 people and also hosted the 2017 ISU World Single Distances Speed Skating Championships in February 2017. Short track speed skating takes place on a smaller rink, normally the size of an ice hockey rink, on a 111.12 m oval track. Distances are shorter than in long-track racing, with the longest Olympic individual race being 1500 meters (the women's relay is 3000 meters and the men's relay 5000 meters). Most speed skating races are held on an oval course, but there are exceptions. Oval sizes vary; in short track speed skating, the rink must be an oval of 111.12 metres, while long track speed skating uses a similarly standardized 400 m rink. Inline skating rinks are between 125 and 400 metres, though banked tracks can only be 250 metres long. Before you use the Speed Calculator, please keep in mind two very important points. First, in Short Track speed skating, the skaters rarely skate the actual measured distance on the track, usually skating a somewhat wider track, and therefore farther than the measured 111.12 meters per lap. If you cannot get a flying lap timed, just enter your best time in a short race, like a 333 (300 for Long Track) or a 500. Just to answer the big question of How fast can a speedskater really skate?, try entering the current (2001) 500 meter World Record for Long Track, 34.32. The long track speed skating track is more than three times the length of the short track. Speed skating is broken up into 12 events at the Olympics for both men and women. Men compete at distances of 500 meters, 1,000 meters, 1,500 meters, 5,000 meters, 10,000 meters and a team event. Speed skating. The standard rink for long track is 400 meters long, but tracks of 200, 250 and 333 meters are used occasionally. It is one of two Olympic forms of the sport and the one with the longer history. An international federation was founded in 1892, the first for any winter sport. Query: how long is a speed skating track
