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 400 metres hurdles is a track and field hurdling event. The event has been on the Olympic athletics programme since 1900 for men and since 1984 for women.
60 metres, or 60-meter dash, is a sprint event in track and field. It is a championship event for indoor championships, normally dominated by the best outdoor 100 metres runners. At indoor events, the 60 metres is run on lanes set out in the middle of the 'field', as is the hurdles event over the same distance, thus avoiding some of the effects of the banked track encircling the venue, upon which other track events in indoor events are run. At outdoor venues it is a rare distance, at least for senior athletes. The format of the event is similar to other sprint distances. The sprinters follow three initial instructions: 'on your marks', instructing them to take up position in the starting blocks; 'set', instructing them to adopt a more efficient starting posture, which also isometrically preloads their muscles. This will enable them to start faster. The final instruction is the firing of the starter's pistol. Upon hearing this the sprinters stride forwards from the blocks.

The 100 metres hurdles, or 100-meter hurdles, is a track and field event run mainly by women. For the race, ten hurdles of a height of 33 inches (83.8 cm) are placed along a straight course of 100 metres (109.36 yd). The first hurdle is placed after a run-up of 13 metres from the starting line. The next 9 hurdles are set at a distance of 8.5 metres from each other, and the home stretch from the last hurdle to the finish line is 10.5 metres long. The hurdles are set up so that they will fall over if bumped into by the runner, but weighted so this is disadvantageous. Fallen hurdles do not count against runners provided that they do not run into them on purpose. Like the 100 metres sprint, the 100 m hurdles begins with athletes in starting blocks.
