Sprint (running)

Sprinting is the act of running over a short distance at (or near) top speed. It is used in many sports that incorporate running, typically as a way of quickly reaching a target or goal, or avoiding or catching an opponent. Human physiology dictates that a runner's near-top speed cannot be maintained for more than 30–35 seconds due to the depletion of Phosphocreatine stores in muscles, and perhaps secondarily to excessive Metabolic acidosis as a result of Anaerobic glycolysis.

In athletics and track and field, sprints (or dashes) are races over short distances. They are among the oldest running competitions. The first 13 editions of the Ancient Olympic Games featured only one event—the stadion race, which was a race from one end of the stadium to the other. There are three sprinting events which are currently held at the Summer Olympics and outdoor World Championships: the 100 metres, 200 metres, and 400 metres. These events have their roots in races of imperial measurements which were later altered to metric: the 100 m evolved from the 100 yard dash, the 200 m distances came from the furlong (or 1/8 of a mile), and the 400 m was the successor to the 440 yard dash or quarter-mile race.

IAAF Diamond League

The IAAF Diamond League is an annual series of track and field meetings held from 2010 onwards, beginning with the 2010 IAAF Diamond League. It was designed to replace the IAAF Golden League, which was held annually since 1998.

While the Golden League was formed to increase the profile of the leading European athletics competitions, the Diamond League's aim is to "enhance the worldwide appeal of athletics by going outside Europe for the first time." In addition to the original Golden League members (except Berlin) and other traditional European meetings, the series includes events in China, Qatar, and the United States.

David Rudisha

David Lekuta Rudisha, MBS (born 17 December 1988) is a Kenyan middle-distance runner. He is the current Olympic champion and world record holder in the 800 metres. Rudisha was the first person to run under 1:41 for the event, and he holds the three fastest, six of the eight fastest, and half of the twenty fastest times ever run in this event. Rudisha has won a record 3 consecutive Track & Field Athlete of the Year awards (tied with Carl Lewis), and also won the IAAF World Athlete of the Year award in 2010.

Early life

Born in Kilgoris, Narok County, Rudisha went to St Patricks High School in Iten, Keiyo District, which is known for nurturing several top runners including Wilson Kipketer, the previous 800 m world record holder, who had already held the record for several years before Rudisha joined the school. In April 2005 Japheth Kimutai recommended Rudisha to James Templeton, and Rudisha joined the group of runners managed by Templeton, which has at various time included Kimutai, Bernard Lagat and Augustine Choge. Initially he was a 400 metres runner, but his coach, Irishman Colm O'Connell, prompted him to try 800 m. In 2006 he became the world junior champion over that distance.

Shanghai Tower

The Shanghai Tower (Chinese: 上海中心大厦; pinyin: Shànghǎi Zhōngxīn Dàshà; literally: "Shanghai Center Tower") is a megatall skyscraper in Lujiazui, Pudong, Shanghai. Designed by Gensler and owned by a consortium of Chinese state-owned companies, it is the tallest of a group of three adjacent supertall buildings in Pudong, the other two being the Jin Mao Tower and the Shanghai World Financial Center. The building is 632 metres (2,073 ft) high and has 128 stories, with a total floor area of 380,000 m² (4,090,000 sq ft). Its tiered construction, designed for high energy efficiency, provides multiple separate zones for office, retail and leisure use. The Shanghai Tower was completed in the summer of 2015.

Construction work on the tower began in November 2008. Following its topping out on 3 August 2013, the Shanghai Tower is currently the tallest building in China and the second-tallest in the world, surpassed only by the Burj Khalifa in Dubai. It was scheduled to open to the public in June 2015, but this has not happened as of late November 2015. It is also China's tallest structure of any kind, surpassing the 600-metre (1,969 ft) Canton Tower in Guangzhou completed in 2010.
