The Chicago Marathon is a marathon held every October in Chicago, Illinois. Alongside the Boston, New York, London, Berlin, and Tokyo Marathons, it is one of the six World Marathon Majors. [1] Thus, it is also an IAAF Gold Label race. The Chicago Marathon is the fourth-largest race by number of finishers worldwide. [2]

Marathon long-distance running event with an official distance of 42.195 kilometres

The marathon is a long-distance race, completed by running, walking, or a run/walk strategy. There are also wheelchair divisions. The marathon has an official distance of 42.195 kilometres, usually run as a road race. The event was instituted in commemoration of the fabled run of the Greek soldier Pheidippides, a messenger from the Battle of Marathon to Athens, who reported the victory.

Boston Marathon marathon running race held in Boston, Untied States

The Boston Marathon is an annual marathon hosted by several cities in greater Boston in eastern Massachusetts, United States. It is always held on Patriots' Day, the third Monday of April. Begun in 1897, the event was inspired by the success of the first marathon competition in the 1896 Summer Olympics. The Boston Marathon is the world's oldest annual marathon and ranks as one of the world's best-known road racing events. It is one of six World Marathon Majors. Its course runs from Hopkinton in southern Middlesex County to Copley Square in Boston.

New York City Marathon marathon running race held in New York, United States

The New York City Marathon is an annual marathon that courses through the five boroughs of New York City. It is the largest marathon in the world, with 52,812 finishers in 2018 and 98,247 applicants for the 2017 race. Along with the Boston Marathon and Chicago Marathon, it is among the pre-eminent long-distance annual running events in the United States and is one of the World Marathon Majors.


The first race was held on September 25, 1977 under the original name the Mayor Daley Marathon, which drew a field of 4,200 runners. The race has been held every year since, except in 1987 when only a half-marathon was run. [3] [4] [5] It is among the fastest growing marathon road races in the world, due in part to its largely fast and flat course which facilitates the pursuit of personal records and world record performances. [6] The race has achieved its elite status among marathons by developing relationships with sponsors who provide prize money to lure elite runners who have produced American and world record performances. Since 2008, the race has been owned and organized by Bank of America, and is officially known as the Bank of America Chicago Marathon.

World record

A world record is usually the best global and most important performance that is ever recorded and officially verified in a specific skill or sport. The book Guinness World Records collates and publishes notable records of all types, from first and best to worst human achievements, to extremes in the natural world and beyond.

The Bank of America Corporation is an American multinational investment bank and financial services company based in Charlotte, North Carolina with central hubs in New York City, London, Hong Kong, Minneapolis, and Toronto. Bank of America was formed through NationsBank's acquisition of BankAmerica in 1998. It is the second largest banking institution in the United States, after JP Morgan Chase. As a part of the Big Four, it services approximately 10.73% of all American bank deposits, in direct competition with Citigroup, Wells Fargo, and JPMorgan Chase. Its primary financial services revolve around commercial banking, wealth management, and investment banking.

The race is limited to 45,000 runners and only runners who finish within 6½ hours are officially timed. [6] Those wishing to participate can register after either meeting a time qualifying standard or being selected through a general lottery. [7] Although the race has limited registration, exceptions include elite runners, legacy finishers, and charity representatives. [8] Increasingly, local, national and global charities as well as humanitarian organizations encourage sponsored participation in the event as a means of fund raising. [9] [10]

The first marathon at the 1896 Games of the I Olympiad generated interest in the sport which led to similar races throughout most western countries and across the United States. While marathons sporadically occurred in New York City and St. Louis, [11] the Boston Marathon had established an annual marathon in 1897, soon to be followed by Chicago. [12] Beginning in 1905, [13] the Chicago Marathon (organized first by the Illinois Athletic Club 1905 to 1909, then sponsored by the Chicago Daily News after 1910) was held annually, with significant community and spectator support, until the early 1920s. [14]

Western world Countries that identify themselves with an originally European—since the Cold War, US American—shared culture

The Western world, also known as the West, refers to various nations depending on the context, most often including at least part of Europe, Australasia, and the Americas, with the status of Latin America in dispute. There are many accepted definitions, all closely interrelated. The Western world is also known as the Occident, in contrast to the Orient, or Eastern world.

The First Chicago Marathon was run on September 23, 1905. [12] That first race began in Evanston and finished in front of a standing-room-only paying crowd at Washington Park race track. In a stunning upset, a reported 100,000 or more spectators watched Rhud Metzner come from behind to steal a late-race victory from the favored Louis Marks. [13] With that first race, the Chicago Marathon began an annual run of epic races that continued until the early 1920s on a revised course that largely resembles today's marathon route. [14] Over the years elite fields included Olympic champions, world records were continually sought, and the marathon continued to inspire Chicago communities and spectators until challenges of the early 1920s sidelined the event. [15]

It was not until the health consciousness of the 1960s that marathon growth gained traction in the eyes of the nation. Frank Shorter's 1972 Games of the XX Olympiad marathon victory represented the convergence of many middle-class American ideals. [16] Then the 1976 New York City Marathon, which was the first New York City Marathon to embrace the five borough course, popularized the big city marathon. As the New York marathon began to grow exponentially in the 1970s, the Chicago Marathon was established as a rival to the New York City Marathon. [3] By the mid-1980s, the Chicago Marathon was ensconced as one of the big four marathons. [17] During the mid-1980s, it was named America's Marathon/Chicago and opened up the way for appearance payments. Joan Benoit Samuelson described the Chicago Marathons of the mid-1980s as "The World's Marathon". [18] The Bank of America Chicago Marathon is an open race with no qualifying time to participate. [6]

Frank Shorter American long-distance runner, Olympic gold medalist

Frank Charles Shorter is an American former long-distance runner who won the gold medal in the marathon at the 1972 Summer Olympics and the silver medal at the 1976 Summer Olympics. His Olympic success, along with the achievements of other American runners, is credited with igniting the running boom in the United States during the 1970s.

The Modern Era Chicago Marathon was founded over the objection of Ed Kelly, Chicago Parks Superintendent who refused permission to run in the parks or along the Lake Michigan lakefront. With the help of Lee Flaherty, the event's founder who operated out of Flair House in the Near North Side community area of Chicago, [19] Chicago Mayor Richard J. Daley's support for the marathon was enlisted. Although Mayor Daley died, his successor Michael Anthony Bilandic approved the race and got Kelly on board. Michael Bilandic, a runner, and his wife actually passed out medals at the first marathon on September 25, 1977. This first edition of the modern Chicago Marathon was called the Mayor Daley Marathon. [20] Flaherty footed the bill for the first race, which had no sponsors. He again footed the bill in 1978 when the race was again called the Mayor Daley Marathon. In 1979, however, Beatrice Foods became the first race sponsor.

In the early years the Chicago Marathon was held in August. [21] It has from its inception with 4,200 runners and 2,128 finishers been one of the nation's largest marathons. The 2000 running was second only to New York. [22] The 1979 and 1980 events, however, continued to be gatherings of amateur runners. By 1982, the race finally had sufficient prize money to attract world class athletes. The 1982 was the first with world class times such as the 2:10:59 by Greg Meyer. [16] By 1983, the Chicago Marathon had achieved its status as one of America's most important marathons. In 1984, Beatrice raised the purse to $250,000 ($50,000 more than New York's). [16] The race had become a legitimate rival to New York and continues to vie for top runners. The 1985 race was spectacular with Steve Jones breaking his own course record (2 seconds short of the world record) and Joan Benoit Samuelson the 1984 Olympic Champion, two-time defending Chicago Marathon Champion and Olympic Bronze Medalist, Rosa Mota and the fourth place Olympic finisher and world record setting Ingrid Kristiansen. Benoit set a record that stood nearly a generation. At that time, it was considered the premier marathon in the United States, if not the world. [23] Although 1986 had 40 world-class runners among the 8,000 participants the times paled in comparison. [24] Beatrice dropped out as a sponsor in 1987. Because of this only a half-marathon race was held that year [5] and the marathon was moved to the spring of 1988 [25] and attracted Heileman Brewing Company to sponsor the 1988 Old Style Chicago Marathon. [26] The race resulted in three women who had been passed over for the 1988 Games of the XXIV Olympiad placing in the top positions. [27] In 1991, Heileman discontinued its sponsorship and both the prize money and performances waned. [28] In 1992, the race again had no sponsorship, but 1993 brought new sponsor LaSalle Bank. [29] In 1994, the race became the LaSalle Bank Chicago Marathon. [30] In 1996, LaSalle Bank purchased the Chicago Marathon from Major Events, Inc., who had purchased the race three years prior from Flaherty. [31] [32] In 1998, the race began using transponder timing. [33] In 2001, when Catherine Ndereba broke the women's world record marathon time, both the men's and women's then-current world records had been set at the Chicago Marathon. [34] For 2008, the race was sponsored by Bank of America following the purchase of LaSalle Bank from ABN Amro to Bank of America, and the new title will be in use. [35]

In 2007, Bank of America acquired LaSalle Bank's parent company ABN AMRO North America in 2007 and assumed the race's title sponsorship. [36] [37] The 2007 race made history with the first ever CEO Marathon Challenge. The race featured a special competition among the CEOs, presidents, company owners and c-suite executives of companies with at least $5 million in annual gross revenue ($2.5 million for women). [38] The 2007 race also made history for having three (men's, women's & men's wheelchair) of its four races decided in the final 100 meters in a day of record setting heat. [39] The race was partially shut down early (after three and a half hours) as temperatures rose to an unseasonably hot 88 °F (31 °C), which surpassed both the temperature records for the Chicago Marathon and official Chicago records for October 7. [40] Over 10,000 registrants chose not to run in the record temperatures, while 10,934 people did not finish (many were called after the course closed early for safety). [4] [39] [41] One runner died, over 30 were hospitalized, and over 400 others sought medical attention. Marathon owner and sponsor Bank of America, which had just acquired LaSalle Bank, has denied culpability. Similar hot conditions have been experienced in other city center races. In 2003, London's The British 10K also had extremely hot weather that affected many runners. [41] [42]

The marathon course is a loop course, starting and ending at Grant Park. From here, the current course winds through 29 of the city's neighborhoods. [43] The course loop can be generally divided into three sections: North, West, and South. In each of these sections, three of the city's main stadiums are near the course's turning points: Wrigley Field to the north; the United Center to the west; and Guaranteed Rate Field to the south. The city's fourth professional stadium, Soldier Field, is located near the start/finish area.

For the first three miles, runners wind through Chicago's downtown area. Eventually, they head north along LaSalle Street.

Runners are supported by over 12,000 volunteers [44] spread throughout the course including at 20 aid stations [45] located approximate every 1–3 miles. [46] For runners in distress, aid station volunteers include medical staff and ambulatory services are scattered throughout the course.

Digital timers are positioned every 5 kilometers, as well as the halfway point.

The Bank of America Chicago Marathon has grown significantly from its beginnings. In 1905, 20 runners registered for the first Chicago Marathon, 15 actually started the race, and 7 finished. [15] For the first "modern" marathon race in 1977, 4,200 people took part. [49] In 1995, 9,000 people registered, and in 1999, over 29,000 people registered. The 2001 marathon run on October 7 reached its cap of 37,500, which was instituted after the 2000 race drew 33,171 runners, [50] just prior to the entry deadline on September 19. [51] In 2003, 2004, 2005, and 2006 it reached its cap of 40,000. [3] [52] The October 10, 2004, October 9, 2005 and October 22, 2006 races reached their 40,000 entrant caps on August 16, July 14, and May 26 respectively. [52] [53] [54] On April 18, 2007, the 2007 race run on October 7 reached its cap of 45,000 entrants. [55] There was a late registration exemption whereby elite runners (marathon times of less than 2:31/3:01 or half marathon times of 1:11/1:21 for (men/women)) could register until September 1 even though the race had reached its registration cap in the spring. [56] The 40,000 registrants and 33,000 finishers in 2003 made the Chicago Marathon the third or fourth largest marathon depending on which metric (registrants or finishers) is used. [57]

The Chicago Marathon is entered by predominantly Caucasian entrants from middle- to upper-middle-class affluence with a wide range in age and near equality in the sexes. [6] The Chicago Marathon has never excluded women. Historically, however, the women's field has been smaller than the men's. This seems to be the result of older age categories having large multiples of men to women, but the women are beginning to outnumber the men in the 20s age group of the field. [58]


World records have been broken at Chicago four times. [59] In 1984, Steve Jones broke the world record with 2:08:05. In 1999, Khalid Khannouchi was the first to surpass 2:06:00 with 2:05:42. The women's record was broken in two consecutive years. In 2001, Catherine Ndereba broke the record in 2:18:47, and Paula Radcliffe surpassed that mark with 2:17:18 the year after.

Radcliffe's world record is also the course record; while the men's record is 2:03:45, set in the 2013 race by Dennis Kimetto. [60]

Economic impact

Much of the marathon's impact is derived from the tourism industry. More than 10,000 of the runners in 2010 indicated that it was their first visit to Chicago. Of that, 6,000 came from 100 countries. Due to the travelers, the event increases hotel occupancy rates during the marathon. According to an independent study by the University of Illinois, the 2015 marathon contributed an estimated US$277 million worth of activity to the Chicago economy, equivalent to 1,948 jobs. [61]

Charity program

Since the charity program was officially established in 2002, more than 106,000 runners have raised over $167 million for local, national and global causes. [62]

Charity fundraising is now closely intertwined with the event as the runners now raise money for research, aid the suffering and heighten public awareness of different causes. [63] The marathon offers all registered entrants the opportunity to fundraise for a charity partner. The marathon recognizes four levels of charities based on the number of participants recruited, and fundraising levels. [64]

Runners can also opt out of the public lottery or obtain a guaranteed place after this has been drawn by choosing to run for an official charity. The 2016 event had over 170 charity partners, and raised more than US$16.9 million. [62]

Pirtea had held a 30-second lead with 600 meters remaining but never looked back as Adere slipped down the right side of the final straightaway under the shield of male runners. Adere was so far to the right that as she crossed the finish line she did not take the tape which was being held at the left side of the finish line. The 2007 Chicago Marathon was the slowest women's Chicago finish since 1992 due to the heat. Pirtea had been a pacemaker at the January 28, 2007, running of the Osaka Ladies Marathon, and an injury prevented her from making her marathon debut at the London Marathon on April 22, 2007.
