Eliud Kipchoge broke the 2-hour mark in a 2019 exhibition

In 2019, Kenya's Kipchoge ran 1:59:40.2, though it was part of an exhibition that included numerous aids—including elite runners cutting his wind and a laser marking the necessary pace—not permitted in officially sanctioned events. As such, it is not eligible for the world record.

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.

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.

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

The races—Tokyo, Boston, London, Berlin, Chicago, Sydney, and New York City—are on some of the best-known courses in the world and are run by some of the sport’s top athletes.

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 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.

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.

Lee Spencer, a single-leg amputee, broke the world record when he rowed solo and unsupported across the Atlantic Ocean in 2019.

Kathrine Switzer was the first official female finisher in the Boston Marathon

A year after Bobbi Gibb’s unofficial finish, Kathrine Switzer registered under an androgynous name to avoid suspicion. Race officials unsuccessfully tried to remove her from the race while she was competing (pictured below), but she ultimately became the first woman to officially finish the race. In 1972, the Boston Marathon changed its rules to allow women to register.

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.

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.

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 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.

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.

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.

An impostor convinced Frank Shorter he’d lost the gold

The 1972 marathon at the Munich Games featured a dramatic finish, thanks to someone posing as a competitor entering the stadium before Shorter. The stunt confused Shorter and the crowd (and enraged the American television announcers) as he entered the final stretch.

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.

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. Beyond these world-historical achievements, the British mathematician also nearly represented his country in the Olympics in the marathon, running just 11 minutes slower than the eventual gold recipient at the 1948 games. Read more on this lesser-known aspect of the man here.

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

The story of Pheidippides is not likely true, but that hasn’t stopped the story from spreading. Much of that is thanks to Robert Browning, who enshrined the myth for a new generation in a 1879 poem that described the man dying after delivering word of the victory.

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.

The tragic story of Jim Peters

At the 1954 Commonwealth Games, Jim Peters, then one of England's best marathoners, was just steps away from victory. He then fell to the ground and staggered about for 11 minutes until medical services took him out of the race. He'd entered the stadium 17 minutes ahead of the pack, but ultimately never finished. It was the last race of his career.

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).

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.

An ‘ultramarathon’ is any race longer than a marathon

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.

Dangers of a record-breaking, sleep-skipping stunt

In 1963, 17-year-old Randy Gardner decided to stay awake for as long as it took to break the current world record. He managed to stay awake for 11 days. In 2017, the then-71-year-old Gardner told NPR that his experience had come back to haunt him as insomnia. The challenge has since been removed from the Guinness Book of World Records due to its dangerous consequences.
