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.
The marathons of Berlin, Boston, Chicago, London, New York City and Tokyo form the World Marathon Majors series, awarding $500,000 annually to the best overall male and female performers in the series.
In 2006, the editors of Runner's World selected a "World's Top 10 Marathons", in which the Amsterdam, Honolulu, Paris, Rotterdam, and Stockholm marathons were featured along with the five mentioned above.
Other notable large marathons include United States Marine Corps Marathon, Los Angeles, and Rome.
The Boston Marathon is the world's oldest annual marathon, inspired by the success of the 1896 Olympic marathon and held since 1897.
The oldest annual marathon in Europe is the Košice Peace Marathon, held since 1924 in Košice, Slovakia.
The historic Polytechnic Marathon was discontinued in 1996.
The Athens Classic Marathon traces the route of the 1896 Olympic course, starting in Marathon on the eastern coast of Attica, site of the Battle of Marathon of 490 B.C.E., and ending at the Panathenaic Stadium in Athens.
The Midnight Sun Marathon is held in Tromsø, Norway at 70 degrees north.
Using unofficial and temporary courses, measured by GPS, races of marathon distance are now held at the North Pole, in Antarctica and over desert terrain.
Other unusual marathons include the Great Wall Marathon on The Great Wall of China, the Big Five Marathon among the safari wildlife of South Africa, the Great Tibetan Marathon – a marathon in an atmosphere of Tibetan Buddhism at an altitude of , and the Polar Circle Marathon on the permanent ice cap of Greenland.
The Intercontinental Istanbul Eurasia Marathon is the only marathon where participants run over two continents (Europe and Asia) during the course of a single event.
In the Detroit Free Press Marathon, participants cross the US/Canadian border twice.
The Niagara Falls International Marathon includes one international border crossing, via the Peace Bridge from Buffalo, New York, United States to Fort Erie, Ontario, Canada.
The 2012 Olympic route differs significantly from that of the long-established annual London Marathon.
Although both events do finish in The Mall, and have a section along the Victoria Embankment in common, the Olympic event also starts in The Mall whilst the London Marathon starts in Greenwich, and the two events follow completely different courses.
The logistical problems behind the design of the London Marathon course (35,000 runners of mixed ability) are very different from those behind the design of the London Olympic Marathon course (100 top-class runners) and therefore it is highly unlikely that the London Marathon would follow the Olympic route, as happened in Atlanta from 1997 to 2009.
Then, the Atlanta Marathon followed most of the Olympic route except for the start and finish which were in the car park of the stadium, which had since been converted to baseball use. 
The Athens Classic Marathon is an annual marathon road race held in Athens, Greece, normally in early November.
The race attracted around 30,000 competitors in 2013, including the concurrent 5 and 10 kilometres road races and the racewalking contest.
The marathon course is based on the myth from which the race gained its name: Pheidippides, a messenger in Ancient Greece, ran from the Battle of Marathon to Athens to announce the Greeks' victory over the Persians.
The provenance of the competitive race is traced back to the Marathon race at the 1896 Olympics.
The Athens Classic Marathon began in 1972 as a joint venture between the Greek tourist board and athletics association.
The race came under the auspices of the current organisers and SEGAS in 1983 and has since become a major race, being awarded Gold Label Road Race status by the IAAF.
It is perhaps one of the most difficult major marathon races: the course is uphill from the 10 km mark to the 31 km mark – the toughest uphill climb of any major marathon.
The course begins in the town of Marathon, where it passes the tomb of the Athenian soldiers, and it traces a path near the coast through Nea Makri.
Following the steep rise, the course goes lightly downhill towards the city of Athens.
It passes a statue of a runner ("Ο Δρομέας") in the city centre before finishing up at the Panathinaiko Stadium; a site for athletics competitions in ancient times and the finishing point for both the 1896 and 2004 Olympic marathons.
In 1982, the organisers dedicated the race to Grigoris Lambrakis, an athlete and Member of the Greek Parliament, whose murder in the 1960s has become an inspirational cause for advocates of human rights.
Since 2007 the Association of International Marathons and Distance Races has organised an annual International Marathon Symposium in Marathon town the day prior to the race.
Taking from the tradition of the Olympic Torch, the race features the Marathon Flame, which is lit at the Tomb of the Battle of Marathon and carried to the stadium in Marathon before the beginning of each race.
The 2010 edition of the event was combined with the celebration of the 2500th anniversary of the Battle of Marathon.
Greek competitors have traditionally been strong in the men's and women's competitions.
However, East Africans and Japanese runners have increasingly become the dominant runners from 1999 onwards.
Since 1990, the Athens Classic Marathon has often served as the Greek national championships for the marathon event.
The current course records are 2:11:35 hours for men, set by Raymond Bett in 2012, while Rasa Drazdauskaitė's run of 2:31:06 in 2010 is the quickest by a woman on the course. 
The route starts and finishes in the Olympic Stadium.
The course is flat, with a maximum elevation of 33ft at the 23rd mile. 
London has hosted the Olympic games on two previous occasions in 1908 and in 1948.
The marathon route was different on both occasions and the 2012 route follows yet another route.
