The 100 metres , or 100-metre dash , is a sprint race in track and field competitions. The shortest common outdoor running distance, it is one of the most popular and prestigious events in the sport of athletics . It has been contested at the Summer Olympics since 1896 for men and since 1928 for women.
The reigning 100 m Olympic champion is often named "the fastest man in the world". The World Championships 100 metres has been contested since 1983. American Justin Gatlin and Tori Bowie are the reigning world champions; Usain Bolt and Elaine Thompson are the Olympic champions in the men's and women's 100 metres, respectively.
On an outdoor 400 metres running track , the 100 m is run on the home straight , with the start usually being set on an extension to make it a straight-line race. Runners begin in the starting blocks and the race begins when an official fires the starter's pistol . Sprinters typically reach top speed after somewhere between 50–60 m. Their speed then slows towards the finish line.
The 10-second barrier has historically been a barometer of fast men's performances, while the best female sprinters take eleven seconds or less to complete the race. The current men's world record is 9.58 seconds, set by Jamaica's Usain Bolt in 2009, while the women's world record of 10.49 seconds set by American Florence Griffith-Joyner in 1988 remains unbroken.
The 100 m (109.361 yards) emerged from the metrication of the 100 yards (91.44 m), a now defunct distance originally contested in English-speaking countries. The event is largely held outdoors as few indoor facilities have a 100 m straight.
US athletes have won the men's Olympic 100 metres title more times than any other country, 16 out of the 28 times that it has been run. US women have also dominated the event winning 9 out of 21 times.
At high level meets, the time between the gun and first kick against the starting block is measured electronically, via sensors built in the gun and the blocks. A reaction time less than 0.1 s is considered a false start . The 0.2-second interval accounts for the sum of the time it takes for the sound of the starter's pistol to reach the runners' ears, and the time they take to react to it.
For many years a sprinter was disqualified if responsible for two false starts individually. However, this rule allowed some major races to be restarted so many times that the sprinters started to lose focus. The next iteration of the rule, introduced in February 2003, meant that one false start was allowed among the field, but anyone responsible for a subsequent false start was disqualified.
This rule led to some sprinters deliberately false-starting to gain a psychological advantage: an individual with a slower reaction time might false-start, forcing the faster starters to wait and be sure of hearing the gun for the subsequent start, thereby losing some of their advantage. To avoid such abuse and to improve spectator enjoyment, the IAAF implemented a further change in the 2010 season – a false starting athlete now receives immediate disqualification.  This proposal was met with objections when first raised in 2005, on the grounds that it would not leave any room for innocent mistakes. Justin Gatlin commented, "Just a flinch or a leg cramp could cost you a year's worth of work."  The rule had a dramatic impact at the 2011 World Championships , when current world record holder Usain Bolt was disqualified. 
Runners normally reach their top speed just past the halfway point of the race and they progressively decelerate in the later stages of the race. Maintaining that top speed for as long as possible is a primary focus of training for the 100 m.  Pacing and running tactics do not play a significant role in the 100 m, as success in the event depends more on pure athletic qualities and technique.
The winner, by IAAF Competition Rules, is determined by the first athlete with his or her torso (not including limbs, head, or neck) over the nearer edge of the finish line.  When the placing of the athletes is not obvious, a photo finish is used to distinguish which runner was first to cross the line.
Climatic conditions, in particular air resistance, can affect performances in the 100 m. A strong head wind is very detrimental to performance, while a tail wind can improve performances significantly. For this reason, a maximum tail wind of 2.0 m/s is allowed for a 100 m performance to be considered eligible for records, or "wind legal".
Furthermore, sprint athletes perform a better run at high altitudes because of the thinner air, which provides less air resistance. In theory, the thinner air would also make breathing slightly more difficult (due to the partial pressure of oxygen being lower), but this difference is negligible for sprint distances where all the oxygen needed for the short dash is already in the muscles and bloodstream when the race starts. While there are no limitations on altitude, performances made at altitudes greater than 1000 m above sea level are marked with an "A". 
Sex and ethnicity
Only male sprinters have beaten the 100 m 10-second barrier , nearly all of them being of West African descent. Namibian (formerly South-West Africa ) Frankie Fredericks became the first man of non-West African heritage to achieve the feat in 1991 and in 2003 Australia's Patrick Johnson (an Indigenous Australian with Irish heritage) became the first sub-10-second runner without an African background.
In 2010, French sprinter Christophe Lemaitre became the first Caucasian to break the 10-second barrier, in 2017, Azerbaijani -born naturalized Turkish Ramil Guliyev followed. In the Prefontaine Classic 2015 Diamond League meet at Eugene , Su Bingtian ran a time of 9.99 seconds, becoming the first Asian athlete to officially break the 10-second barrier. On 9 September 2017, Yoshihide Kiryū became the first man from Japan to break the 10-second barrier in the 100 meters, running a 9.98 (+1.8) at an intercollegiate meet in Fukui . In the 2015 Birmingham Grand Prix Diamond League meet, British athlete Adam Gemili , who is of mixed Iranian and Moroccan descent, ran a time of 9.97 seconds on home soil, becoming the first athlete with either North African or Middle Eastern heritage to break the ten-second barrier.
Colin Jackson , an athlete with mixed ethnic background and former world record holder in the 110 metre hurdles , noted that both his parents were talented athletes and suggested that biological inheritance was the greatest influence, rather than any perceived racial factor. Furthermore, successful black role models in track events may reinforce the racial disparity.
Major 100 m races, such as at the Olympic Games, attract much attention, particularly when the world record is thought to be within reach.
The men's world record has been improved upon twelve times since electronic timing became mandatory in 1977. The current men's world record of 9.58 s is held by Usain Bolt of Jamaica, set at the 2009 World Athletics Championships final in Berlin , Germany on 16 August 2009, breaking his own previous world record by 0.11 s. The current women's world record of 10.49 s was set by Florence Griffith-Joyner of the US, at the 1988 United States Olympic Trials in Indianapolis , Indiana, on 16 July 1988 breaking Evelyn Ashford 's four-year-old world record by .27 seconds. The extraordinary nature of this result and those of several other sprinters in this race raised the possibility of a technical malfunction with the wind gauge which read at 0.0 m/s- a reading which was at complete odds to the windy conditions on the day with high wind speeds being recorded in all other sprints before and after this race as well as the parallel long jump runway at the time of the Griffith-Joyner performance. All scientific studies commissioned by the IAAF and independent organizations since have confirmed there was certainly an illegal tailwind of between 5 m/s - 7 m/s at the time. This should have annulled the legality of this result, although the IAAF has chosen not to take this course of action. The legitimate next best wind legal performance would therefore be Griffith-Joyner's 10.61s performance in the final the next day.
Jim Hines , Ronnie Ray Smith and Charles Greene were the first to break the 10-second barrier in the 100 m, all on 20 June 1968, the Night of Speed . Hines also recorded the first legal electronically timed sub-10 second 100 m in winning the 100 metres at the 1968 Olympics . Bob Hayes ran a wind-assisted 9.91 seconds at the 1964 Olympics.

More facts about these male runners
- Usain Bolt also holds the record for the fastest 100 metres with a running start at 8.70 (41 km/h). This was achieved during a 150 metres race in Manchester 2009, completed in 14.35 (also a World Record). He also ran times of 9.63 (2012), 9.69, 9.72 (2008), 9.76 (2008, 2011, 2012), 9.77 (2008, 2013), 9.79 (2009, 2012, 2015), 9.80 (2013), 9.81 (2009, 2016), 9.82 (2010, 2012), 9.83 (2008), 9.84 (2010), 9.85 (2008, 2011, 2013), 9.86 (2009, 2010, 2012, 2016), 9.87 (2012, 2015) and 9.88 (2011, 2016)
- Justin Gatlin ran 9.77 in Doha on 12 May 2006, which was at the time ratified as a world record. However, the record was rescinded in 2007 after he failed a doping test in April 2006. He also ran times of 9.74 (2015), 9.75 (2015), 9.77 (2014), 9.78 (2015), 9.79 (2012), 9.80 (2014, 2015, 2016), 9.82 (2014), 9.83 (2014, 2015), 9.85 (2004, 2013), 9.86 (2014), 9.88 (2005)
- Tim Montgomery 's time of 9.78 at Paris on 14 September 2002 was rescinded following his indictment in the BALCO scandal on drug use and drug trafficking charges. The time had stood as the world record until Asafa Powell first ran 9.77.
- Ben Johnson ran 9.79 at Seoul on 24 September 1988, but he was disqualified after he tested positive for stanozolol after the race. He subsequently admitted to drug use between 1981 and 1988, and his time of 9.83 at Rome on 30 August 1987 was rescinded. Carl Lewis's 9.92 in the Seoul race was therefore recognised as the world record, and his two prior runs of 9.93 were seen as having equalled the previous world record.
- Ato Boldon ran four 9.86 races (two in 1998, two in 1999).
- Dwain Chambers time of 9.87 (+2.0) on 14 September 2002 in Paris was later annulled due to doping offence.
- Steve Mullings is serving a lifetime ban for doping.
- Jimmy Vicaut also ran 9.86 and 9.88 in June 2016.

More facts about these female runners
- Florence Griffith-Joyner 's world record has been the subject of a controversy due to strong suspicion of a defective anemometer measuring a tailwind lower than actually present;  since 1997 the International Athletics Annual of the Association of Track and Field Statisticians has listed this performance as "probably strongly wind assisted, but recognised as a world record".  It can be reasonable to assume a wind reading of about +4.7 m/s for Griffith-Joyner's quarter-final. Her 10.61 the following day and 10.62 at the 1988 Olympics would still make her the world record holder. 
Below is a list of all other legal times equal or superior to 10.77:
