400 metres

The 400 metres, or 400 metre dash, is a common sprinting event in track and field competitions. It has been featured in the athletics programme at the Summer Olympics since 1896 (1964 for women). On a standard outdoor running track, it is exactly one lap around the track. Runners start in staggered positions and race in separate lanes for the entire course. In many countries, athletes previously competed in the 440 yard dash (402.336 m)—which is the length of a quarter of a mile and was referred to as the 'quarter-mile'—instead of the 400 m (437.445 yards), though this distance is now obsolete. An athlete who competes in the 400 m may still be referred to as 'quarter-miler'; the distance or event might still be called the "quarter."

Maximum sprint speed capability is a significant contributing factor to success in the event, but athletes also require substantial speed endurance and the ability to cope well with high amounts of lactic acid to sustain a fast speed over a whole lap. While considered to be predominantly an anaerobic event, there is some aerobic involvement and the degree of aerobic training required for 400 metre athletes is open to debate.

Red Bull

Red Bull is an energy drink sold by Austrian company Red Bull GmbH, created in 1987. In terms of market share, Red Bull is the highest-selling energy drink in the world, with 5.387 billion cans sold in 2013.

Austrian entrepreneur Dietrich Mateschitz was inspired by an existing energy drink named Krating Daeng, which was first invented and sold in Thailand. He took this idea, modified the ingredients to suit the tastes of Westerners, and, in partnership with Chaleo Yoovidhya, founded Red Bull GmbH in 1987 in Chakkapong, Thailand. In Thai, daeng means red, and krating is the large bovine called "gaur". Red Bull is sold in a tall and slim blue-silver can, while Krating Daeng is in a gold shorter can. The two are different products, produced separately.

The Red Bull company slogan is "Red Bull gives you wings", and the product is marketed through advertising, events (Red Bull Cliff Diving World Series, Red Bull Air Race, Red Bull Crashed Ice), sports team ownerships (RB Leipzig, FC Red Bull Salzburg, Red Bull Brasil, New York Red Bulls, Red Bull Racing, Scuderia Toro Rosso), celebrity endorsements, and music, through its record label Red Bull Records.

Michael Phelps

Michael Fred Phelps II (born June 30, 1985) is an American competition swimmer and the most decorated Olympian of all time, with a total of 22 medals in three Olympiads. Phelps also holds the all-time records for Olympic gold medals (18, double the second highest record holders), Olympic gold medals in individual events (11), and Olympic medals in individual events for a male (13). In winning eight gold medals at the 2008 Beijing Games, Phelps took the record away from fellow swimmer Mark Spitz (7) for the most first-place finishes at any single Olympic Games. Five of those victories were in individual events, tying the single Games record. In the 2012 Summer Olympics in London, Phelps won four golds and two silver medals, making him the most successful athlete of the Games for the third Olympics in a row.

Phelps is the long course world recordholder in the 100-meter butterfly, 200-meter butterfly and 400-meter individual medley as well as the former long course world recordholder in the 200-meter freestyle and 200-meter individual medley. He has won a total of 77 medals in major international long-course competition, totalling 61 gold, 13 silver, and 3 bronze spanning the Olympics, the World, and the Pan Pacific Championships. Phelps's international titles and record-breaking performances have earned him the World Swimmer of the Year Award seven times and American Swimmer of the Year Award nine times as well as the FINA Swimmer of the Year Award in 2012. His unprecedented Olympic success in 2008 earned Phelps Sports Illustrated magazine's Sportsman of the Year award.

World record

A world record is usually the best global performance ever recorded and officially verified in a specific skill or sport. The book Guinness World Records collates and publishes notable records of all types, from first and best to worst human achievements, to extremes in the natural world and beyond. The website RecordSetter has begun to take on the same territory, but with a more inclusive policy, as users submit videos of record attempts in order to try to receive a world record. The website challengers.guinnessworldrecords.com is similar to RecordSetter, as the record attempts are judged by Guinness World Records adjudicators, but the records to attempt are provided beforehand.

Terminology

In the United States the form World's Record was formerly more common. The term World Best was also briefly in use. The latter term is still used in athletics events, including track and field and road running) to describe good and bad performances not recognized as an official world record: either because the event is a non-qualifying event (e.g. the 150 m run or individual events in a decathlon), or because it does not fulfil other criteria of an otherwise qualifying event (e.g. the Great North Run half-marathon, which has an excessive downhill gradient). The term is also used in video game speedrunning when someone achieves the fastest possible time for the game and category.
