There are over 800 annual marathons, but only seven deemed World Marathon Majors

The marathon is only getting more popular

The marathon has become a part of popular culture, with races in nearly every major city. The largest is the New York City Marathon, which started in 1970. Over 55,000 runners participated in the 2024 race. Its popularity doesn’t appear to be slowing, with younger generations increasingly lacing up their shoes for the race of a lifetime.

Why marathons are 26.2 miles (not 26)

Over 1,100 marathons are run every year, and they all share one oddly specific distance: 26.2 miles. From ancient Greece to a British queen's request, here's the surprising story behind the marathon's decimal.

The first modern marathon was at the 1896 Olympic Games

The modern marathon was created for the revived Olympic Games in 1896, with the course starting in Marathon and ending in Athens. The race was won by Spiridon Louis, a Greek water carrier who surged in the last stretch to the delight of the hometown crowd.

The marathon was not an event in the ancient form of the Olympics

The ancient Olympics started with just one footrace, a roughly 3-mile jaunt dubbed the "dolichos." Over the centuries, it blossomed into multiple running events, field events, combat sports, and equestrian events—all performed in the nude. This list showcases eight more lesser-known facts about the ancient Games.

Gen Z is increasingly interested in running marathons

The race has become a popular event for young people. Over 12,000 20-somethings signed up for the New York Marathon in 2024. That's a significant increase from 2023 (9.987) and 2022 (8,039).

Chris Nikic is the first person with Down syndrome to complete several marathons

In March 2024, Chris Nikic finished the Tokyo Marathon in 5:39:41. That was the final step towards his ultimate goal of earning the Abbott World Marathon Majors Six Star Finisher distinction. It recognizes runners who have finished Tokyo, Boston, London, Berlin, Chicago and New York.

An ‘ultramarathon’ is any race longer than a marathon

The event is a catchall for any event longer than a marathon, with some races hundreds of miles long. Despite the inherent risks, including death, the sport has exploded in recent years.

The first Boston Marathon was held the next year

In 1897, the manager of the US Olympic team organized the first Boston Marathon, which featured a field of 15 runners. The race took place on Patriots Day, a holiday commemorating the first battles of the American Revolution.

The modern marathon’s arbitrary distance is thanks to the British royal family

In 1908, the London Games set the marathon distance to 26.2 miles to meet the British royal family’s request that the race start at Windsor Castle and end at their royal box. In 1921, that arbitrary distance became the official length for the marathon.

The oldest marathoner was 100

Fauja Singh was 100 when he completed the Toronto Waterfront Marathon in 2011 at 8:11:06. Incredibly Singh didn't start running until the age of 89.

The 1904 Olympic marathon was a bizarre spectacle

When the Olympics first came to the US, the race was still a fringe event with few established rules. That led to an absurd comedy, with competitors ingesting poison, hitchhiking 11 miles of the course, and occasionally sipping brandy.

The marathon’s roots can be traced back to a Greek myth

Legend has it that the first marathon took place in 490 BCE, when Pheidippides, an ancient Greek soldier, ran from the Battle of Marathon back to Athens—approximately 25 miles—to inform his people they’d defeated the Persians. The story is likely apocryphal: No Greek historian mentioned it until over 500 years later.

The PGA Tour features over 30 tournaments per year, but the most important are its 4 majors: the Masters, the PGA Championship, the US Open, and the Open Championship.

Frank Shorter was the first American to win the 26.2-mile Olympic marathon

The Adidas shoes that helped break the marathon's 2-hour barrier

Two men broke the two-hour mark at the 2026 London Marathon, a feat previously unofficially achieved only by Eliud Kipchoge, thanks to a number of aides not permitted in an official race. Both men who broke the two-hour barrier in London wore the same shoe, the Adizero Adios Pro Evo 3, a new model that weighs just over three ounces.

Ultrarunning has grown exponentially in the 21st century

Ultrarunning, generally defined as races 50k and longer, has exploded in the past few decades. In 2000, there were 89 official races; in 2023, there were nearly 760. That's a 753% increase.

Watch Kipchoge break 2 hours in the marathon

The feat was once considered impossible, but one of the world's greatest marathoners got to work (with the help of a team of scientists and some of the world's most elite distance runners) to break that boundary in Vienna in 2019. The final stretch of the run is an emotional moment for Kipchoge, who doesn't even appear to be winded.

In 1980, a woman cheated her way to a Boston Marathon win

Rosie Ruiz, an unknown runner, finished first in the Boston Marathon, cutting her qualifying New York time by over 20 minutes. The world would soon learn, though, that Ruiz hadn't run the entirety of either race, something that her first interviewer seems to piece together by her strange answers to basic questions.

Runners typically burn 2,600 calories during a marathon

They also burn between 5-10 pounds of water weight, often feel more focused and elated (thanks to increased neurotransmitters), and, oddly enough, temporarily grow about a half-inch shorter due to back muscles tensing.

Joan Benoit was the first woman to win Olympic marathon gold

Benoit was the first woman to win Olympic gold in the 1984 Los Angeles Games marathon, running 2:24:52. She also won the Boston Marathon twice and held the Chicago Marathon record for 32 years. She’s still going, too, running Boston in a blistering 3:04 at age 61 in 2019.

Some Nike shoes are actually making runners too fast

In 2018, Kenyan runner Eliud Kipchoge lowered the world marathon record to 2:01:39 in a pair of Nike Vaporflys. The unusually thick running shoes sparked controversy around the shoe regulations for professional runners.

An impostor convinced Frank Shorter he’d lost the gold

Women were prohibited from the Boston Marathon, so Bobbi Gibb snuck in

Race directors assumed women could not handle the physical demands of the race. In 1966, Bobbi Gibb hid in the bushes near the starting line, then hopped in the race after it began, and became the first woman to finish the Boston Marathon, albeit unofficially.

Running became more popular in the mid-20th century

Heat-related complications are of greater concern for distance runners than cardiac threats

Analysis of more than 130,000 runners in Tel Aviv events during a seven-year period indicated that the runners were 10 times more likely to experience heatstroke than serious cardiac problems. Scientists suggest that runners should take 10 to 14 days to acclimate to a hot climate before tackling a serious run.

The 2026 Milan-Cortina Games are the most geographically spread out ever

As part of the planning committee's efforts to reduce costs and minimize infrastructure impact, existing ski resorts, rinks, and stadiums were used for the Winter Olympics in northern Italy. This inherently spreads events out, with venues scattered over a roughly 8,500-square-mile area of the country. See a map of the venues here.

Computer pioneer Alan Turing was also an elite runner

Alan Turing is credited with helping to found modern computer science, in addition to cracking the Nazi code known as Enigma.

Read more on this lesser-known aspect of the man here.

Robert Browning memorialized the marathon myth in a 19th-century poem
