Events

Track and field events are divided into three broad categories: track events, field events, and combined events. The majority of athletes tend to specialise in just one event (or event type) with the aim of perfecting their performances, although the aim of combined events athletes is to become proficient in a number of disciplines. Track events involve running on a track over a specified distances and—in the case of the hurdling

s in which teams of athletes run and pass on a baton to their team member at the end of a certain distance.

There are two types of field events: jumps, and throws. In jumping competitions, athletes are judged on either the length or height of their jumps. The performances of jumping events for distance are measured from a board or marker, and any athlete overstepping this mark is judged to have fouled. In the jumps for height, an athlete must clear his or her body over a crossbar without knocking the bar off the supporting standards. The majority of jumping events are unaided, although athletes propel themselves vertically with purpose-built sticks in the pole vault

.

The throwing events involve hurling an implement (such as a heavy weight, javelin or discus) from a set point, with athletes being judged on the distance that the object is thrown. Combined events involve the same group of athletes contesting a number of different track and field events. Points are given for their performance in each event and the athlete with the greatest points total at the end of all events is the winner.

Sprints

Races over short distances, or sprints, are among the oldest running competitions. The first 13 editions of the Ancient Olympic Games featured only one event – the stadion race, which was literally a race from one end of the stadium to the other. Sprinting events are focused around athletes reaching and sustaining their quickest possible running speed. There are three sprinting events which are currently held at the Olympics and outdoor World Championships: the 100 metres
100 metres

Athletes remain in the same lane on the running track throughout all sprinting events, with the sole exception of the 400 m indoors.

 may also be classified as a middle distance event. The 880 yard run, or half mile, was the forebear of the 800 m distance and it has its roots in competitions in the United Kingdom in the 1830s. The 1500 m came about as a result of running three laps of a 500 m track, which was commonplace in continental Europe in the 20th century.

Runners start the race from a standing position along a curved starting line and after hearing the starter's pistol they head towards the innermost track to follow the quickest route to the finish. In 800 m races athletes begin at a staggered starting point before the turn in the track and they must remain in their lanes for the first 100 m of the race. This rule was introduced in order to reduce the amount of physical jostling between runners in the early stages of the race. Physiologically, these middle distance events demand that athletes have good aerobic

Relays

Relay races are the only track and field event in which a team of runners directly compete against other teams. Typically, a team is made up of four runners of the same sex. Each runner completes their specified distance (referred to as a leg) before handing over a baton to a team mate, who then begins their leg upon receiving the baton. There is usually a designated area in which athletes must exchange the baton. Teams may be disqualified if they fail to complete the change within the area, or if the baton is dropped during the race. A team may also be disqualified if its runners are deemed to have wilfully impeded other competitors.
Relay races emerged in the United States in the 1880s as a variation on charity races between firemen

 featured in 1908 Olympics. The 4×100 m event is run strictly within the same lane on the track, meaning that the team collectively runs one complete circuit of the track. Teams in a 4×400 m event remain in their own lane until the runner of the second leg passes the first bend, at which point runners can leave their lanes and head towards the inner-most part of the circuit. For the second and third baton change overs, team mates must align themselves in respect of their team position – leading teams take the inner lanes while team mates of the slower teams must await the baton on outer lanes.

The IAAF keeps world records for five different types of track relays. As with 4×100 m and 4×400 m events, all races comprise teams of four athletes running the same distances, with the less commonly contested distances being the 4×200 m, 4×800 m

Long jump

) were held in each hand during the jump then swung back and dropped near the end in order to gain extra momentum and distance. The modern long jump, standardised in England and the United States around 1860, bears resemblance to the ancient event although no weights are used. Athletes sprint along a length of track which leads up to a jumping board and a sandpit

Triple jump

Similar to the long jump, the triple jump takes place on a track heading towards a sandpit. Originally, athletes would hop on the same leg twice before jumping into the pit, but this was changed to the current "hop, step and jump" pattern from 1900 onwards. There is some dispute over whether the triple jump was contested in ancient Greece: while some historians claim that a contest of three jumps occurred at Ancient Games, others such as Stephen G. Miller believe this to be incorrect, suggesting that the belief stems from a mythologised account of Phayllus of Croton having jumped 55 ancient feet (around 16.3 m). The Book of Leinster

Athletes have a short run up and then take off from one foot to jump over a horizontal bar and fall back onto a cushioned landing area. The men's high jump was included in the 1896 Olympics and a women's competition soon followed in 1928.

 poles were introduced in the 20th century and a metal box in the runway for planting the pole became standard. Landing matresses were introduced in the mid-20th century to protect the athletes who were clearing increasingly greater heights.

The modern event sees athletes run down a strip of track, plant the pole in the metal box, and vault over the horizontal bar before letting go of the pole and falling backwards onto the landing matress. While earlier versions used wooden, metal or bamboo, modern poles are generally made from artificial materials such as fibreglass or carbon fibre.

 throwing competitions within the English military provided a precursor to the modern sport. The modern rules were first laid out in 1860 and legal throws had to be taken within a square throwing area of seven feet (2.13 m) on each side. This was amended to a circle area with a seven foot diameter in 1906 and the weight of the shot was standardised to 16 pounds (7.26 kg). Throwing technique was also refined over this period, with bent arm throws being banned as they were deemed too dangerous and the side-step and throw technique arising in the United States in 1876. Shot Putters are generally the largest and most explosive athletes on a team.

The shot put has been an Olympic sport for men since 1896 and a women's competition using a 4 kg (8.82 lb) shot was added in 1948. Further throwing techniques have arisen since the post-war era: in the 1950s Parry O'Brien

, and it was this style that was revived for the 1896 Olympics. This continued until the 1906 Intercalated Games in Athens, which featured both the ancient style and the increasingly popular modern style of turning and throwing. By the 1912 Olympics, the ancient standing throw style had fallen into disuse and contests starting within a 2.5 m squared throwing area became the standard. The discus implement was standardised to 2 kg (4.4 pounds) in weight and 22 cm (8 inches) in diameter in 1907. The women's discus was among the first women's events on the Olympic programme, being introduced in 1928.

 throwing began in prehistoric times. Along with the discus, the javelin was the second throwing event in the ancient Olympic pentathlon. Records from 708 BC show two javelin competition types co-existing: throwing at a target and throwing the javelin for distance. It was the latter type from which the modern event was derived. In ancient competitions, athletes would wrap an ankyle (thin leather strip) around the javelin which acted as a sling to gain extra distance. The javelin throw gained much popularity in Scandinavia

 in the late 18th century and athletes from the region continue to be among the most dominant throwers in men's competitions. The modern event features a short run up on a track and then the thrower releases the javelin before the foul line.

 introduced a hollow javelin, then a metal javelin, both of which increased throwers performances. Another former athlete, Miklós Németh invented the rough-tailed javelin and throws reached in excess of 100 m – edging towards the limits of stadia. The distances and the increasing number of horizontal landings led the IAAF to redesign the men's javelin to reduce distance and increase the implement's downward pitching moment

 to allow for easier measurement. Rough-tailed designs were banned in 1991 and all marks achieved with such javelins were removed from the record books. The women's javelin underwent a similar redesign in 1999. The current javelin specifications are 2.6 to 2.7 m in length and 800 grams in weight for men, and between 2.2 to 2.3 m and 600 g for women.

Hammer throw

The earliest recorded precursors to the modern hammer throw stem from the Tailteann Games around 1800 BC, which featured events such as throwing either a weight attached to a rope, a large rock on a wooden handle, or even a chariot
Chariot
The chariot is a type of horse carriage used in both peace and war as the chief vehicle of many ancient peoples. Ox carts, proto-chariots, were built by the Proto-Indo-Europeans and also built in Mesopotamia as early as 3000 BC. The original horse chariot was a fast, light, open, two wheeled...

s were recorded. The hammer implement was standardised in 1887 and the competitions began to resemble the modern event. The weight of the metal ball was set at 16 pounds (7.26 kg) while the attached wire had to measure between 1.175 m and 1.215 m.

The men's hammer throw became an Olympic event in 1900 but the women's event – using a 4 kg (8.82 lb) weight – was not widely competed until much later, finally featuring on the women's Olympic programme a century later. The distance's thrown by male athletes became greater from the 1950s onwards as a result of improved equipment using the denser metals, a switch to concrete throwing areas, and more advanced training techniques. Professional hammer throwers as historically large, strong, sturdy athletes. However, qualities such as refined technique, speed and flexibility have become increasingly important in the modern era as the legal throwing area has been reduced from 90 to 34.92 degrees and throwing technique involves three to four controlled rotations.

Track rules

The rules of track athletics or of track events in athletics as observed in most international athletics competitions are set by the Competition Rules of the International Association of Athletics Federations
International Association of Athletics Federations
The International Association of Athletics Federations is the international governing body for the sport of athletics. It was founded in 1912 at its first congress in Stockholm, Sweden by representatives from 17 national athletics federations as the International Amateur Athletics Federation...

 (IAAF). The most recent complete set of rules is the 2009 rules that relate only to competitions in 2009. Key rules of track events are those regarding starting, running and finishing.

Starting

The start of a race is marked by a white line 5 cm wide. In all races that are not run in lanes the start line must be curved, so that all the athletes start the same distance from the finish.
Starting blocks may be used for all races up to and including 400 m (including the first leg of the 4 x 100 m and 4 x 400 m) and may not be used for any other race. No part of the starting block may overlap the start line or extend into another lane.
All races must be started by the report of the starter's gun or approved starting apparatus fired upwards after he or she has ascertained that athletes are steady and in the correct starting position. An athlete may not touch either the start line or the ground in front of it with his or her hands or feet when on his or her marks.
At most international competitions the commands of the starter in his or her own language, in English or in French, shall, in races up to and including 400 m, be "On your marks" and "Set". When all athletes are "set", the gun must be fired, or an approved starting apparatus must be activated. However, if the starter is not satisfied that all is ready to proceed, the athletes may be called out of the blocks and the process started over.

False start: An athlete, after assuming a final set position, may not commence his starting motion until after receiving the report of the gun, or approved starting apparatus. If, in the judgment of the starter or recallers, he does so any earlier, it is considered a false start. It is deemed a false start if, in the judgment of the starter an athlete fails to comply with the commands "on your marks" or "set" as appropriate after a reasonable time; or an athlete after the command "on your marks" disturbs other athletes in the race through sound or otherwise. If the runner is in the "set" position and moves, then the runner is also disqualified. , any athlete making a false start is disqualified. This rule was already in place in high school and college.

In International Elite competition, electronically tethered starting blocks sense the reaction time of the athletes. If the athlete reacts in less than 0.1 second, an alert sounds for a recall starter and the offending athlete is guilty of a false start.

Running the race

In all races run in lanes, each athlete must keep within his allocated lane from start to finish. This also applies to any portion of a race run in lanes. If an athlete leaves the track or steps on the line demarking the track, he/she should be disqualified. Also, any athlete who jostles or obstructs another athlete, in a way that impedes his progress, should be disqualified from that event. However, if an athlete is pushed or forced by another person to run outside his lane, and if no material advantage is gained, the athlete should not be disqualified.

There are races that start in lanes and then at a "break" line, the competitors merge. Examples of this are the 800 metres, 4x400 relay and the indoor 400 metres. Variations on this, with alleys made up of multiple lanes on the track, are used to start large fields of distance runners.

The finish

The finish of a race is marked by a white line 5 cm wide. The athletes must be placed in the order in which any part of their torso (as distinguished from the head, neck, arms, legs, hands or feet) reaches the vertical plane of the nearer edge of the finish line. Fully automatic timing systems (photo timing) are becoming more and more common at increasingly lower levels of track meets, improving the accuracy, while eliminating the need for eagle-eyed officials on the finish line. Fully automatic timing (FAT) is required for high level meets and any time a (sprint) record is set (though distance records can be accepted if timed by three independent stopwatches).

With the accuracy of the timing systems, ties are rare. Ties between different athletes are resolved as follows: In determining whether there has been a tie in any round for a qualifying position for the next round based on time, a judge (called the chief photo finish judge) must consider the actual time recorded by the athletes to one thousandth of a second. If the judge decides that there has been a tie, the tying athletes must be placed in the next round or, if that is not practicable, lots must be drawn to determine who must be placed in the next round. In the case of a tie for first place in any final, the referee decides whether it is practicable to arrange for the athletes so tying to compete again. If he decides it is not, the result will stand. Ties in other placings remain.

Field rules

In general, most field events allow a competitor to take their attempt individually, under theoretically the same conditions as the other competitors in the competition. Each attempt is measured to determine who achieved the longest distance.

Vertical jumps (High Jump and Pole Vault) set a bar at a particular height. The competitor must clear the bar without knocking it off the standards that are holding the bar (flat). Three failures in a row will end the competitor's participation in the event. The competitor has the option to PASS their attempt, which can be used to strategic advantage (of course that advantage is lost if the competitor misses). A pass could be used to save energy and avoid taking a jump that would not improve their position in the standings. After all competitors have either cleared, passed or failed their attempts at a height, the bar will go up. The amount the bar goes up is predetermined before the competition, though when one competitor remains, that competitor may choose their own heights for the remaining attempts. A record is kept of each attempt by each competitor. After all competitors have taken their attempts, the one jumping the highest is the winner, and so on down the other competitors in the event. Ties are broken by first, the number of attempts taken at the highest height (fewest wins), and then if still tied, by the total number of misses in the competition as a whole. The bar does not go back to a lower height except to break a tie for first place or a qualifying position. If those critical positions are still tied after applying the tiebreakers, all tied competitors will take a fourth jump at the last height. If they still miss, the bar will go down one increment where they will again jump. This process will continue until the tie is broken.

Horizontal jumps (Long Jump and Triple Jump) and all throws must be initiated behind a line. In the case of horizontal jumps, that line is a straight line perpendicular to the runway. In the case of throws, that line is an arc or a circle. Crossing the line while initiating the attempt will invalidate the attempt—it will become a foul. All landings must occur in a sector. For the jumps, that is a sand filled pit, for throws it is a defined sector. A throw landing on the line on the edge of sector is a foul (the inside edge of the line is the outside edge of the sector). Assuming a proper attempt, officials will then measure the distance from the closest landing point back to the line. The measuring tape is carefully straightened to the shortest distance between the point and the line. To accomplish this, the tape must be perfectly perpendicular to the take off line in jumps, or is pulled through the center point of the arc for throws. The officials at the landing end of the tape have the zero, while the officials at the point of initiation will see the length and record the measurement. Whenever a record (or potential record) occurs, that measurement is taken (again) using a steel tape and observed by at least three officials (plus usually the meet referee). Steel tapes tend to be easily bent and damaged, so they are not used to measure everyday competitions. For major competitions, each competitor will get three attempts. The top competitors (usually 8 or 9 depending on that competition's rules or the number of lanes on the track) will get three more attempts. At that level of competition, the order of competitors for those final three attempts are set in order so the competitor in first place at the end of the third round will be last, while the last competitor to qualify will go first. Some meets will rearrange the competition order again for the final round so the final attempt will be taken by the leader at that point. At other competitions, meet management may choose to limit all competitors to four or three attempts. Whatever the format, all competitors get an equal number of attempts.

Organizations

Meetings

Records

Athletes performances are timed or measured at virtually all track and field competitions. Doing so can not only serve as a way of determining the winner in an event, but it can also be used for historical comparison (i.e. a record). A large variety of record types exist and men's and women's performances are recorded separately. The foremost types of records are those which organise athlete's performances by the region which they are representing: beginning with national records

 level. National governing bodies control the national record lists, the area associations organise their respective continental lists, and the IAAF is the body which ratifies world records.
The IAAF ratifies track and field world records if they meet their set criteria. The IAAF first published a world records list in 1914, initially for men's events only. There were 53 recognised records in running, hurdling and relay, and 12 field records. World records in women's events began in 1936 as more events were gradually added to the list, but significant changes were made in the late 1970s. First, all records in imperial measurements were abandoned in 1976, with the sole exceptional being the mile run due to the prestige and history of the event. The following year, all world records in sprint events would only be recognised if fully automatic electronic timing was used (as opposed to the traditional hand-timing stopwatch method). In 1981, electronic timing was made compulsory for all world record runs in track and field, with times being recorded to within one hundredth of a second. Two additional types of world record were introduced in 1987: world records for indoor competitions, and world records for junior athletes under 20 years old.

The next most important record type are those achieved at a specific competition – for example the Olympic records which are the best performances by athletes during events at the Summer Olympics. All major championships and games have their relevant competition records and a large number of track and field meetings keep a note of their meet records. Other record types include: stadium records, records by age range, records by disability, and records by institution or organisation. Cash bonuses are usually offered to athletes if they break significant records, as doing so can generate greater interest and public attendance in track and field competitions.

Doping

Track and field athletes are banned from ingesting or using certain substances by governing bodies for the sport, from the national to the global level. The IAAF's constitution incorporates the World Anti-Doping Code among other anti-doping measures. Practices such as blood doping

s, or diuretics can give athletes a physical competitive advantage in track and field. The use of such substances in track and field is opposed on both ethical and medical grounds. Given that the sport functions by measuring and comparing athletes' performances, performance-enhancing substances create an uneven playing field — athletes who do not use doping substances have a disadvantage over rivals who do. Medically, the use of banned substances may have an adverse effect upon athletes' health. However, some exemptions are made for athletes who take banned substances for therapeutic use, and athletes are not sanctioned for usage in these cases, such as Kim Collins

However, the use of substances not on the prohibited list may also result in sanctions if the substance is deemed to be similar to a banned substance in either composition or effect.
