Roberta Joan "Joni" Mitchell is a Canadian-American singer-songwriter, multi-instrumentalist, and painter. As one of the most influential singer-songwriters to emerge from the 1960s folk music circuit, Mitchell became known for her personal lyrics and unconventional compositions which grew to incorporate pop and jazz elements. Among her accolades are eleven Grammy Awards, and induction into the Rock and Roll Hall of Fame in 1997. Rolling Stone called her "one of the greatest songwriters ever", and AllMusic has stated, "Joni Mitchell may stand as the most important and influential female recording artist of the late 20th century."
Sprinting is running over a short distance at the top-most speed of the body in a limited period of time. 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.
A relay race is a racing competition where members of a team take turns completing parts of racecourse or performing a certain action. Relay races take the form of professional races and amateur games. Relay races are common in running, orienteering, swimming, cross-country skiing, biathlon, or ice skating. In the Olympic Games, there are several types of relay races that are part of track and field, each consisting of a set number of stages (legs), each leg run by different members of a team. The runner finishing one leg is usually required to pass the next runner a stick-like object known as a "baton" while both are running in a marked exchange zone. In most relays, team members cover equal distances: Olympic events for both men and women are the 400-metre and 1,600-metre relays. Some non-Olympic relays are held at distances of 800 m, 3,200 m, and 6,000 m. In the less frequently run medley relays, however, the athletes cover different distances in a prescribed order—as in a sprint medley of 200, 200, 400, 800 metres or a distance medley of 1,200, 400, 800, 1,600 metres.
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.
The 400 metres, or 400-meter dash, is a sprint event in track and field competitions. It has been featured in the athletics programme at the Summer Olympics since 1896 for men and since 1964 for women. On a standard outdoor running track, it is 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 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.
Irena Szewińska was a Polish sprinter who was one of the world's foremost track athletes for nearly two decades, in multiple events. She won a total of seven Olympic medals including three golds. She is the only athlete in history, male or female, to have held the world record in the 100 m, the 200 m and the 400 m events. She was voted the Polish Sports Personality of the Year four times. In 2016, she was awarded Poland's highest decoration, the Order of the White Eagle.
The 4 × 400 metres relay or long relay is an athletics track event in which teams consist of four runners who each complete 400 metres or one lap, totaling 1600 meters. It is traditionally the final event of a track meet. The first leg and the first bend of the second leg are run in lanes. Start lines are thus staggered over a greater distance than in an individual 400 metres race; the runners then typically move to the inside of the track. The slightly longer 4 × 440 yards relay, on an Imperial distance, was a formerly run British Commonwealth and American event, until metrication was completed in the 1970s.
Monique Hennagan is an American athlete who mainly competes in the 400 metres. She won her first relay medal at the 1999 World Indoor Championships and her second in 2003.
Stephanie Louise Rice, OAM is an Australian former competitive swimmer. She won three gold medals at the 2008 Summer Olympics in Beijing, and was awarded the Medal of the Order of Australia on 26 January 2009.
