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

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 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.

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 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.

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

The running legend became the first American to win the 26.2-mile Olympic marathon in 1972 at 2:21:19. The televised race contributed to a nationwide running boom and helped popularize the event.

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.

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.

Modern tennis was formalized in 1874

In the late 1800s England, a growing middle class could afford homes with lawns. With more lawns in England, Major Walter C. Wingfield saw an opportunity to bring lawn tennis to the masses. Modern tennis was formalized in 1874, when Queen Victoria granted a patent for Major Walter C. Wingfield's lawn tennis box set. The game was an instant hit, and by 1877, the new All England Club in Wimbledon began hosting a tournament.

The first official Formula One World Championship race was in 1950

On May 13, 1950, Formula 1 held its first race at Silverstone in the UK. Over 150,000 people, including the British monarch (and future Queen Elizabeth II), turned out to watch the field of 28 cars over the 70-lap race. The race wasn’t very competitive, but it’s still a fascinating artifact to observe.

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.

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.

Since 1983, the meter has been defined based on the speed of light

The 1875 Metre Convention established the unit as the length between two lines inscribed on the surface of bars made by the International Bureau of Weights and Measures. Advancements in the measurement of light redefined it as the distance light travels in 1/299,792,458 of a second.
