The name Marathon comes from the legend of Pheidippides, the Greek messenger. The legend states that while he was taking part in the Battle of Marathon, which took place in August or September 490 BC,{{cite web|title=Astronomers Unravel Marathon Mystery|url=http://www.skyandtelescope.com/press-releases/astronomers-unravel-marathon-mystery-2/|website=Sky & Telescope|access-date=21 March 2017|date=19 July 2004|archive-url=https://web.archive.org/web/20170211130116/http://www.skyandtelescope.com/press-releases/astronomers-unravel-marathon-mystery-2/|archive-date=11 February 2017|url-status=live}} he witnessed a Persian vessel changing its course towards Athens as the battle was near a victorious end for the Greek army.

The account of the run from Marathon to Athens first appeared in Plutarch's On the Glory of Athens in the first century AD, which quoted from Heraclides Ponticus's lost work, giving the runner's name as either Thersipus of Erchius or Eucles.Moralia 347C Satirist Lucian of Samosata gave one of the earliest accounts similar to the modern version of the story, but its historical veracity is disputed based on its tongue-in-cheek writing and the runner being referred to as Philippides and not Pheidippides.{{Cite web |title=The Myth of Pheidippides and the Marathon |url=http://www.findingdulcinea.com/news/sports/2010/april/Myth-of-Pheidippides-and-the-Marathon.html |url-status=live |archive-url=https://web.archive.org/web/20181106143318/http://www.findingdulcinea.com/news/sports/2010/april/Myth-of-Pheidippides-and-the-Marathon.html |archive-date=6 November 2018 |access-date=7 May 2019 |website=findingdulcinea.com|date=4 November 2011 }}{{cite web|url=http://lucianofsamosata.info/wiki/doku.php?id=home:texts_and_library:essays:a-slip-of-the-tongue-in-salutation#section3|title=A slip of the tongue in salutation, Chapter 3; The Works of Lucian of Samosata.

{{wikisource|Pheidippides}}

In 1879, Robert Browning wrote the poem Pheidippides. Browning's poem, his composite story, became part of late 19th-century popular culture and was accepted as a historical legend.{{cite magazine|url=http://www.runnersworld.com/running-tips/oct-26-truth-about-pheidippides-and-early-years-marathon-history|title=The Truth about Pheidippides and the Early Years of Marathon History|last=Burfoot|first=Amby|date=26 October 2010|magazine=Runner's World|access-date=25 December 2014|archive-url=https://web.archive.org/web/20141225062715/http://www.runnersworld.com/running-tips/oct-26-truth-about-pheidippides-and-early-years-marathon-history|archive-date=25 December 2014|url-status=live}}

Mount Pentelicus stands between Marathon and Athens, which means that Philippides would have had to run around the mountain, either to the north or to the south. The latter and more obvious route is followed by the modern Marathon-Athens highway (EO83–EO54), which follows the lay of the land southwards from Marathon Bay and along the coast, then takes a gentle but protracted climb westwards towards the eastern approach to Athens, between the foothills of Mounts Hymettus and Penteli, and then gently downhill to Athens proper. As it existed when the Olympics were revived in 1896, this route was approximately {{convert|40|km|mi}} long. It was the approximate distance originally used for marathon races. However, there have been suggestions that Philippides might have followed another route: a westward climb along the eastern and northern slopes of Mount Penteli to the pass of Dionysos, and then a straight southward downhill path to Athens. This route is slightly shorter, {{convert|35|km|mi}}, but includes a very steep climb over the first {{convert|5|km|mi}}.

{{main|Marathons at the Olympics}}

When the modern Olympics began in 1896, the initiators and organizers were looking for a great popularizing event, recalling the glory of ancient Greece. The idea of a marathon race came from Michel Bréal, who wanted the event to feature in the first modern Olympic Games in 1896 in Athens. This idea was heavily supported by Pierre de Coubertin, the founder of the modern Olympics, as well as by the Greeks.{{cite book|author1=Richard Benyo|author2=Joe Henderson|title=Running Encyclopedia|url=https://archive.org/details/runningencyclope00rich|url-access=registration|year=2002|publisher=Human Kinetics|isbn=9780736037341|pages=[https://archive.org/details/runningencyclope00rich/page/250 250]|access-date=6 April 2017}} A selection race for the Olympic marathon was held on 22 March 1896 (Gregorian){{efn|This date is specified as 10 March in some sources as Greece used the Julian calendar at the time.}} that was won by Charilaos Vasilakos in 3 hours and 18 minutes.{{cite journal|url=http://library.la84.org/SportsLibrary/JOH/JOHv7n1/JOHv7n1d.pdf|title=That Memorable First Marathon|author1=Anthony Bijkerk|author2=David C.

The Boston Marathon began on 19 April 1897 and was inspired by the success of the first marathon competition in the 1896 Summer Olympics. It is the world's oldest annual marathon and ranks as one of the world's most prestigious road racing events. Its course runs from Hopkinton in southern Middlesex County to Copley Square in Boston.

Course officials add a short course prevention factor of up to one meter per kilometer to their measurements to reduce the risk of a measuring error producing a length below the minimum distance.

For events governed by IAAF rules, the route must be marked so that all competitors can see the distance covered in kilometers. The rules do not mention the use of miles. The IAAF will only recognize world records established at events run under IAAF rules. For major events, it is customary to publish competitors' timings at the midway mark and also at 5 km splits; marathon runners can be credited with world records for lesser distances recognized by the IAAF (such as 20 km, 30 km and so on) if such records are established while the runner is running a marathon and completes the marathon course.{{cite web|url=http://www.iaaf.org/mm/Document/Competitions/TechnicalArea/05/47/81/20091027115916_httppostedfile_CompRules2010_web_26Oct09_17166.pdf |title=IAAF Competition Rules 2010–2011 |pages=230–235 |publisher=IAAF |access-date=10 October 2011 |url-status=dead |archive-url=https://web.archive.org/web/20110512013129/http://www.iaaf.org/mm/Document/Competitions/TechnicalArea/05/47/81/20091027115916_httppostedfile_CompRules2010_web_26Oct09_17166.pdf |archive-date=12 May 2011 }}

World records were not officially recognized by the IAAF, now known as World Athletics, until 1 January 2004; previously, the best times for the marathon were referred to as the 'world best'. Courses must conform to World Athletics standards for a record to be recognized. However, marathon routes still vary greatly in elevation, course, and surface, making exact comparisons impossible. Typically, the fastest times are set over relatively flat courses near sea level, during good weather conditions and with the assistance of pacesetters.{{Cite web|url=https://rw.runnersworld.com/sub-2/|title=Runner's World {{!}} What Will It Take to Run A 2-Hour Marathon|website=rw.runnersworld.com|access-date=2017-08-28|archive-url=https://web.archive.org/web/20170829032300/https://rw.runnersworld.com/sub-2/|archive-date=29 August 2017|url-status=live}}

Most participants do not run a marathon to win. More important for most runners is their personal finishing time and their placement within their specific gender and age group, though some runners just want to finish. Strategies for completing a marathon include running the whole distance and a run–walk strategy. In 2005, the average marathon time in the U.S. was 4 hours 32 minutes 8 seconds for men, 5 hours 6 minutes 8 seconds for women.

{{cite web|url=http://www.marathonguide.com/features/Articles/2005RecapOverview.cfm|title=2005 Total USA Marathon Finishers|publisher=Marathonguide.com|access-date=24 April 2008|archive-url=https://web.archive.org/web/20080317061003/http://www.marathonguide.com/features/Articles/2005RecapOverview.cfm|archive-date=17 March 2008|url-status=live}}

In 2015, the men's and women's median marathon times were 4 hours 20 minutes 13 seconds and 4 hours 45 minutes 30 seconds respectively.

A goal many runners aim for is to break certain time barriers. For example, recreational first-timers often try to run the marathon under four hours; more competitive runners may attempt to finish under three hours.{{cite web|url=http://www.allaboutrunning.net/sri-chinmoy-racesblog/running-sub-3-hour-marathon |title=Running a sub 3-hour marathon |publisher=allaboutrunning.net |access-date=22 August 2009 |url-status=usurped |archive-url=https://web.archive.org/web/20090215181724/http://www.allaboutrunning.net/sri-chinmoy-racesblog/running-sub-3-hour-marathon |archive-date=15 February 2009 }} Other benchmarks are the qualifying times for major marathons. The Boston Marathon, the oldest marathon in the United States, requires a qualifying time for all non-professional runners.{{cite web |url=http://www.bostonmarathon.org/BostonMarathon/Qualifying.asp |title=Boston Athletic Association |publisher=Bostonmarathon.org |access-date=22 August 2009 |archive-url=https://web.archive.org/web/20090608141549/http://www.bostonmarathon.org/BostonMarathon/Qualifying.asp |archive-date=8 June 2009 |url-status=dead}} The New York City Marathon also requires a qualifying time for guaranteed entry, at a significantly faster pace than Boston's.{{Cite web|url=https://www.tcsnycmarathon.org/run-in-2017|title=Run in 2017|date=7 September 2016|website=TCS New York City Marathon|access-date=7 May 2019|archive-url=https://web.archive.org/web/20190503130030/https://www.tcsnycmarathon.org/run-in-2017|archive-date=3 May 2019|url-status=live}}

Typically, there is a maximum allowed time of about six hours after which the marathon route is closed, although some larger marathons keep the course open considerably longer (eight hours or more). Many marathons around the world have such time limits by which all runners must have crossed the finish line. Anyone slower than the limit will be picked up by a sweeper bus. In many cases the marathon organizers are required to reopen the roads to the public so that traffic can return to normal.

With the growth in popularity of marathon-running, many marathons across the United States and the world have been filling to capacity faster than ever before. When the Boston Marathon opened up registration for its 2011 running, the field capacity was filled within eight hours.[https://www.boston.com/sports/marathon/articles/2010/10/19/marathon_fills_its_field_in_a_record_8_hours/?page=2 Online, sprinters win race: Marathon fills its field in a record 8 hours] {{Webarchive|url=https://web.archive.org/web/20101022030447/http://www.boston.com/sports/marathon/articles/2010/10/19/marathon_fills_its_field_in_a_record_8_hours/?page=2 |date=22 October 2010 }}.

Many training programs last a minimum of five or six months, with a gradual increase in the distance run and finally, for recovery, a period of tapering in the one to three weeks preceding the race. For beginners wishing to merely finish a marathon, a minimum of four months of running four days a week is recommended.Whitsett et al. (1998) The Non-Runner's Marathon Trainer.

The last long training run might be undertaken up to two weeks prior to the event. Many marathon runners also "carbo-load" (increase carbohydrate intake while holding total caloric intake constant) during the week before the marathon to allow their bodies to store more glycogen.

{{Main|Hitting the wall}}

Carbohydrates that a person eats are converted by the liver and muscles into glycogen for storage. Glycogen burns rapidly to provide quick energy. Runners can store about 8 MJ or 2,000 kcal worth of glycogen in their bodies, enough for about 30 km/18–20 miles of running. Many runners report that running becomes noticeably more difficult at that point.{{cite web|url=http://www.half-marathon-running.com/HittingTheWall |archive-url=https://web.archive.org/web/20170322111711/http://www.half-marathon-running.com/HittingTheWall |url-status=dead |archive-date=22 March 2017 |title=Hitting the wall for marathon runners |publisher=Half-marathon-running.com |access-date=22 August 2009 }} When glycogen runs low, the body must then obtain energy by burning stored fat, which does not burn as readily. When this happens, the runner will experience dramatic fatigue and is said to "hit the wall". The aim of training for the marathon, according to many coaches,{{cite web |url=http://e-articles.info/e/a/title/Lesser-Known-Dangers-Associated-With-Marathons/ |title=Lesser-known Dangers Associated with Running a Marathon |last=Klein |first=Michael |date=3 October 2008 |work=E-articles.info |archive-url=https://web.archive.org/web/20130117044405/http://e-articles.info/e/a/title/Lesser-Known-Dangers-Associated-With-Marathons/ |archive-date=17 January 2013}} is to maximize the limited glycogen available so that the fatigue of the "wall" is not as dramatic. This is accomplished in part by utilizing a higher percentage of energy from burned fat even during the early phase of the race, thus conserving glycogen.{{citation needed|date=July 2012}}

Carbohydrate-based "energy gels" are used by runners to avoid or reduce the effect of "hitting the wall", as they provide easy to digest energy during the run. Energy gels usually contain varying amounts of sodium and potassium and some also contain caffeine. They need to be consumed with a certain amount of water. Recommendations for how often to take an energy gel during the race range widely.

Alternatives to gels include various forms of concentrated sugars, and foods high in simple carbohydrates that can be digested easily. Many runners experiment with consuming energy supplements during training runs to determine what works best for them. Consumption of food while running sometimes makes the runner sick. Runners are advised not to ingest a new food or medicine just prior to or during a race. It is also important to refrain from taking any of the non-steroidal anti-inflammatory class of pain relievers (NSAIDs, e.g., aspirin, ibuprofen, naproxen), as these drugs may change the way the kidneys regulate their blood flow and may lead to serious kidney problems, especially in cases involving moderate to severe dehydration. NSAIDS block the COX-2 enzyme pathway to prevent the production of prostaglandins. These prostaglandins may act as inflammation factors throughout the body, but they also play a crucial role in maintenance of water retention. In less than 5% of the whole population that take NSAIDS, individuals may be more negatively sensitive to renal prostaglandin synthesis inhibition.{{cite journal|last=Brater|first=D.

In 2016, a systematic medical review found that the risk of sudden cardiac death during or immediately after a marathon was between 0.6 and 1.9 deaths per 100,000 participants, varying across the specific studies and the methods used, and not controlling for age or gender.{{cite journal |journal=The Physician and Sportsmedicine |volume=44 |issue=1 |date=January 2016 |title=Sudden cardiac death in marathons: a systematic review |vauthors=Waite O, Smith A, Madge L, Spring H, Noret N |pages=79–84 |doi=10.1080/00913847.2016.1135036 |pmid=26765272 |s2cid=36458482 |url=http://ray.yorksj.ac.uk/id/eprint/1282/1/Waite%20et%20al%202016.pdf |access-date=19 March 2018 |archive-url=https://web.archive.org/web/20170921225307/https://ray.yorksj.ac.uk/id/eprint/1282/1/Waite%20et%20al%202016.pdf |archive-date=21 September 2017 |url-status=live}} Since the risk is small, cardiac screening programs for marathons are uncommon. However, this review was not an attempt to assess the overall cardiac health impact of marathon running.

A 2006 study of non-elite Boston Marathon participants tested runners for certain proteins that indicate heart damage or dysfunction (see Troponin) and gave them echocardiogram scans, before and after the marathon.

According to a Canadian study presented in 2010, running a marathon can temporarily result in decreased function of more than half the muscle segments in the heart's main pumping chamber, but neighboring segments are generally able to compensate. Full recovery is reached within three months. The fitter the runner, the less the effect. The runners with decreased left ventricle function had an average peak weekly training distance of {{convert|55.1|km|abbr=on}}, while those who did not averaged {{convert|69.1|km|abbr=on}}.

It was Lucero's second marathon.{{cite news|title=Fluid Cited in Marathoner's Death|url=https://apnews.com/424edce6ed89d8adcb14d4d97c0448a3|access-date=14 March 2014|work=Associated Press News|date=13 August 2002|archive-url=https://web.archive.org/web/20140419014128/http://www.apnewsarchive.com/2002/Fluid-Cited-in-Marathoner-s-Death/id-424edce6ed89d8adcb14d4d97c0448a3|archive-date=19 April 2014|url-status=live}} At mile 22, Lucero complained of feeling "dehydrated and rubber-legged."{{cite book|last=Noakes, MD, DSc|first=Tim|title=Waterlogged|date=1 May 2012|publisher=Human Kinetics|isbn=978-1450424974|page=4|url=https://books.google.com/books?id=3_zPW6FyqgAC&q=waterlogged|access-date=13 December 2015|archive-url=https://web.archive.org/web/20160521181405/https://books.google.com/books?id=3_zPW6FyqgAC&printsec=frontcover&dq=waterlogged&hl=en&sa=X&ei=mM8jU5PjII7xkQecv4HICw&ved=0CCwQ6AEwAA#v=onepage&q=waterlogged&f=false|archive-date=21 May 2016|url-status=live}} She soon wobbled and collapsed to the ground, and was unconscious by the time the paramedics reached her.

Lucero's cause of death was determined to be hyponatremic encephalopathy, a condition that causes swelling of the brain due to an imbalance of sodium in the blood known as exercise-associated hyponatremia (EAH). While EAH is sometimes referred to as "water intoxication", Lucero drank large amounts of Gatorade during the race,{{cite news|title=Doctors: Marathoner Died From Too Much Water|url=http://www.wcvb.com/Doctors-Marathoner-Died-From-Too-Much-Water/11334548|access-date=14 March 2014|newspaper=WCVB News|archive-url=https://web.archive.org/web/20140419012323/http://www.wcvb.com/Doctors-Marathoner-Died-From-Too-Much-Water/11334548|archive-date=19 April 2014|url-status=live}}{{cite news|last=Nearman|first=Steve|title=Too much of a good thing|url=http://www.washingtontimes.com/news/2003/oct/23/20031023-114721-5381r/?page=all|access-date=14 March 2014|newspaper=The Washington Times|date=23 October 2003|archive-url=https://web.archive.org/web/20140419014642/http://www.washingtontimes.com/news/2003/oct/23/20031023-114721-5381r/?page=all|archive-date=19 April 2014|url-status=live}} demonstrating that runners who consume sodium-containing sports drinks in excess of thirst can still develop EAH.{{cite journal |vauthors=Almond CS, Shin AY, Fortescue EB, etal |title=Hyponatremia among runners in the Boston Marathon |journal=N.

Women are more prone to hyponatremia than men. A study in the New England Journal of Medicine found that 13% of runners completing the 2002 Boston Marathon had hyponatremia.{{Cite journal |vauthors=Almond CS, Shin AY, Fortescue EB, etal |title=Hyponatremia among runners in the Boston Marathon |journal=The New England Journal of Medicine |volume=352 |issue=15 |pages=1550–6 |date=April 2005 |pmid=15829535 |doi=10.1056/NEJMoa043901|s2cid=42909509 |doi-access=free }}

The International Marathon Medical Directors Association (IMMDA) advised in 2006 that fluid intake should be adjusted individually according to factors such as body weight, sex, climate, pace, fitness (VO₂ max), and sweat rate, as fluid requirements can vary between people depending on these variables. The IMMDA also recommended sports drinks that include carbohydrates and electrolytes instead of plain water and said that runners should "drink to thirst", trying to refrain from drinking at every fluid station before feeling thirsty.{{cite web|url=http://aimsworldrunning.org/guidelines_fluid_replacement.htm|title=IMMDA's REVISED FLUID RECOMMENDATIONS FOR RUNNERS & WALKERS|date=6 May 2006|author=Writing committee: Lewis G.

A patient suffering hyponatremia can be given a small volume of a concentrated salt solution intravenously to raise sodium concentrations in the blood. Some runners weigh themselves before running and write the results on their bibs. If anything goes wrong, first aid workers can use the weight information to tell if the patient had consumed too much water.

Exertional heat stroke is an emergency condition in which thermoregulation fails and the body temperature rises dangerously above {{convert|40|C|F}}. It becomes a greater risk in warm and humid weather, even for young and fit individuals. Treatment requires rapid physical cooling of the body.{{cite journal |journal=Medicine & Science in Sports & Exercise |volume=39 |issue=3 |date=March 2007 |title=American College of Sports Medicine position stand: Exertional heat illness during training and competition |pages=556–572 |doi=10.1249/MSS.0b013e31802fa199 |pmid=17473783 | last1 = Armstrong | first1 = LE | last2 = Casa | first2 = DJ | last3 = Millard-Stafford | first3 = M | last4 = Moran | first4 = DS | last5 = Pyne | first5 = SW | last6 = Roberts | first6 = WO|s2cid=27001417 | doi-access = free }}

Some charities seek to associate with various races. Some marathon organizers set aside a portion of their limited entry slots for charity organizations to sell to members in exchange for donations. Runners are given the option to sign up to run particular races, especially when marathon entries are no longer available to the general public.{{Citation needed|date = May 2012}} In some cases, charities organize their own marathon as a fund-raiser, gaining funds via entry fees or sponsorships.{{Citation needed|date=November 2023}}
