The decathlon is a combined event in athletics consisting of 10 track and field events. The word "decathlon" was formed, in analogy to the word "pentathlon", from Greek δέκα and ἄθλος. Events are held over two consecutive days and the winners are determined by the combined performance in all. Performance is judged on a points system in each event, not by the position achieved. The decathlon is contested mainly by male athletes, while female athletes typically compete in the heptathlon.
The World Athletics Championships are a biennial athletics competition organized by World Athletics. Alongside the Olympic Games, they represent the highest level championships of senior international outdoor athletics competition for track and field athletics globally, including marathon running and race walking. Separate World Championships are held by World Athletics for certain other outdoor events, including cross-country running and half-marathon, as well as indoor and age-group championships.
The 100 metres, or 100-meter dash, is a sprint race in track and field competitions. The shortest common outdoor running distance, the 100-meter (109.36 yd) dash 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 inaugural World Championships were in 1983.
The 200 metres, or 200-meter dash, is a sprint running event. On an outdoor 400 metre racetrack, the race begins on the curve and ends on the home straight, so a combination of techniques is needed to successfully run the race. A slightly shorter race, called the stadion and run on a straight track, was the first recorded event at the ancient Olympic Games. The 200 m places more emphasis on speed endurance than shorter sprint distances as athletes predominantly rely on anaerobic energy system during the 200 m sprint. Similarly to other sprint distances, the 200 m begins from the starting blocks. When the sprinters adopt the 'set' position in the blocks they are able to adopt a more efficient starting posture and isometrically preload their muscles. This enables them to stride forwards more powerfully when the race begins and start faster.

The 10-second barrier is the physical and psychological barrier of completing the 100 metres sprint in under ten seconds. The achievement is traditionally regarded as the hallmark of a world-class male sprinter. Its significance has become less important since the late 1990s, as an increasing number of runners have surpassed the ten seconds mark. The current men's world record holder is Usain Bolt, who ran a 9.58 at the 2009 IAAF World Championship competition.
