Why marathons are 26.2 miles (not 26)

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

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 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.

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

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.

The evolution of the Olympics from ancient Greece to the modern world

The Olympic Games have evolved from a sacred footrace in 776 BCE honoring Zeus to a global celebration of athletic excellence and unity.
