Track running in the context of "3000 metres"

Paula Jane Radcliffe (born 17 December 1973) is a British former long-distance runner. She is a three-time winner of the London Marathon (2002, 2003, 2005), three-time New York Marathon champion (2004, 2007, 2008), the 2002 Chicago Marathon winner and the 2005 World Champion in the Marathon from Helsinki. She was previously the fastest female marathoner of all time, and held the Women's World Marathon Record with a time of 2:15:25 for 16 years from 2003 to 2019 when it was broken by Brigid Kosgei.

Radcliffe is a former world champion in the marathon, half marathon and cross country. She has also been European champion over 10,000 metres and in cross country. On the track, Radcliffe won the 10,000 metres silver medal at the 1999 World Championships and was the 2002 Commonwealth champion at 5000 metres. She represented Great Britain at the Olympics in four consecutive games (1996 to 2008), although she never won an Olympic medal.

The 5K run is a long-distance road running competition over a distance of five kilometres (3.107 mi). Also referred to as the 5K road race, 5 km, or simply 5K, it is the shortest of the most common road running distances. It is usually distinguished from the 5000 metres track running event by stating the distance in kilometres, rather than metres.

Among road running events, the 5K distance is mostly popular with novice or infrequent runners or joggers as it is comparatively easier to complete the distance without endurance training. The 5K distance also makes the distance suitable for people looking to improve or maintain their general physical fitness, rather than develop long-distance running abilities. The brevity of the distance means that less time is required to take part in the activity and that people from a wide range of ages and abilities may participate. From a physiological perspective, five kilometres is towards the low end of endurance running.

The 10K run is a long-distance road running competition over a distance of ten kilometres (6.2 miles). Also referred to as the 10K road race, 10 km, or simply 10K, it is one of the most common types of road running event, alongside the shorter 5K and longer half marathon and marathon. It is usually distinguished from the 10,000 metres track running event by stating the distance in kilometres, rather than metres.

As one of the shortest common road distances, many 10K races attract high levels of public participation. Among the largest 10K races, the Peachtree Road Race in Atlanta, United States had over 55,000 participants in 2011, while the Vancouver Sun Run and Bolder Boulder both had close to 50,000 runners. The popularity of 10K races lies in the fact that, for most adults, the 10K distance is long enough to represent a challenge but short enough to remain accessible for an untrained runner.

The 800 metres, or 800 meters (US spelling), is a common track running event. It is the shortest commonly run middle-distance running event. The 800 metres is run over two laps of an outdoor (400-metre) track and has been an Olympic event since the first modern games in 1896. During the winter track season the event is usually run by completing four laps of an indoor 200-metre track.

The event was derived from the imperial measurement of a half mile (880 yards), a traditional British racing distance. 800 m is 4.67 m less than a half mile.
