Running 2 Final

Marathon

The marathon is a long-distance running event with an official distance of 42.195 kilometres (26 miles and 385 yards), that is usually run as a road race.
The length of a marathon was not fixed at first, since the only important factor was that all athletes competed on the same course. The marathon races in the first few Olympic Games were not of a set length, but were approximately 40 kilometres (25 mi), roughly the distance from Marathon to Athens by the longer, flatter route. The exact length of the Olympic marathon varied depending on the route established for each venue. The standard distance for the marathon race was set by the International Amateur Athletic Federation (IAAF) in May 1921 at a distance of 42.195 kilometres (26 miles 385 yards).

Annually, more than 500 marathons are organized worldwide. Some of these belong to the Association of International Marathons and Distance Races (AIMS) which has grown since its foundation in 1982 to embrace over 300 member events in 83 countries and territories. Five of the largest and most prestigious races, Boston, New York City, Chicago, London and Berlin, form the biennial World Marathon Majors series, awarding $500,000 annually to the best overall male and female performers in the series.

World records were not officially recognized until January 1, 2004.
 previously, the best times for the marathon were referred to as the 'world best'.
The world record time for men over the distance is 2 hours 3 minutes and 59 seconds, set in the Berlin Marathon by Haile Gebrselassie of Ethiopia on September 28, 2008, an improvement of 51 minutes and 19 seconds since Johnny Hayes' gold medal performance at the 1908 summer Olympics. Gebrselassie's world record represents an average pace of under 2:57 per kilometre (4:44 per mile), average speed of over 20.4 km/h (12.6 mph).
The world record for women was set by Paula Radcliffe of Great Britain in the London Marathon on April 13, 2003, in 2 hours 15 minutes and 25 seconds. This time was set using male pacesetters; the fastest time by a woman without using a male pacesetter ("woman-only") was also set by Paula Radcliffe, again during the London Marathon, with a time of 2 hours 17 minutes and 42 seconds, on April 17, 2005.
