'''Speed skiing''' is the [[sport]] of [[skiing]] downhill in a straight line at as high a speed as possible, as timed over a fixed stretch of ski slope. There are two types of contest: breaking an existing speed record or having the fastest run at a given competition. Speed skiers regularly exceed {{convert|200|km/h|mph|0}}

==History==
Speed skiing dates from 1898 with a run by [[United States|American]] Tommy Todd, reported at {{convert|87|mph}}. Official records began with an {{convert|89|mph|abbr=on}} run by Leo Gasperl in 1932. While training for the [[Alpine skiing at the 1956 Winter Olympics|1956 Winter Olympics]], American downhiller [[Ralph Miller (alpine skier)|Ralph Miller]] is credited with being the first to break {{convert|100|mph|0|abbr=on}}, at nearly {{convert|109|mph|abbr=on}} in August<!--26--> 1955 at [[Portillo, Chile]], a record which held up for fifteen years.<ref name=arupwn>{{cite magazine |url=https://vault.si.com/vault/1955/09/05/a-roundup-of-the-weeks-news |magazine=Sports Illustrated |title=A roundup of the week's news: record breakers |date=September 5, 1955 |page=4}}</ref><ref name=hfcigo>{{cite news |url=https://books.google.com/books?id=mFgEAAAAMBAJ&pg=PA11 |magazine=Skiing Heritage<!--Journal-->|title=How fast can I go? |last=Miller |first=Peter |date=September 1999 |page=11}}</ref><ref name=skhrj>{{cite news |url=https://books.google.com/books?id=KK6VKM0njdwC&pg=PA12 |magazine=Skiing Heritage<!--Journal-->|title=Ralph Miller: from wax room to classroom |last=Masia |first=Seth |date=June 2009 |page=12}}</ref>

==Description==
Speed skiing is practiced on steep, specially designed courses {{convert|1|km|sp=us|spell=in}} in length. There are approximately thirty of these courses worldwide, many of them at high altitudes to minimize air resistance. The first {{convert|300|or|400|m|abbr=on}} of the course (the launching area) is used to gain speed, the top speed is measured in the next {{convert|100|m|abbr=on}} (the timing zone) and the last {{convert|500|m|abbr=on}} (the run-out area) is used for slowing down and coming to a stop. The start point in [[International Ski Federation|FIS]] races is chosen so that, in theory, skiers should not exceed {{convert|200|km/h|mph|0}}, hence competition is aimed at winning a particular event, not breaking world speed records. At pro races, there is no maximum speed and the speed attained is determined by conditions and safety.<ref name = Curveball/>

In theory, speeds could continue to increase by using even longer and steeper slopes; this would eventually change speed skiing into something closer to [[skydiving]] except with skis rather than a parachute.  Since a slight bump or gentle turn can easily prove fatal at such speeds, there is little appetite for this.<ref>{{cite book |last=Munroe |first=Randall |date=2019 |title=how to: Absurd Scientific Advice for Common Real-World Problems |location=New York |publisher=Penguin |page=150 |isbn=9780525537090 |author-link=Randall Munroe}}</ref>

==Equipment==
Speed skiers wear dense foam fairings on their lower legs and [[aerodynamic]] [[helmet]]s to increase [[Streamliner|streamlining]]. Their [[ski suit]]s are made from air-tight [[latex]] or have a [[polyurethane]] coating to reduce wind resistance, with only a minimal (but mandatory) back protector to give some protection in the case of a crash.<ref name = Curveball>

The special [[ski]]s used must be {{height|cm=240}} in length and at most {{convert|10|cm|in|abbr=on}} wide, with a maximum weight of {{convert|15|kg|abbr=on}} for the pair. [[Ski boot]]s are attached to the skis by [[ski binding|bindings]]. The [[ski pole]]s are bent to shape around the body, with a minimum length of {{convert|1|m|in|1|abbr=off|sp=us}}.<ref name = Curveball/>
