Spartathlon is one of the most prestigious ultramarathons in the world. It is a race of about 246 km (153 miles), that takes place each September in Greece, running from Athens to Sparta on a highly significant route in world history. It attracts many of the greatest ultrarunners in the world.

This is part one of a series on the history of Spartathlon. In this episode, we will cover how Spartathlon was born in 1982, a story that has never been fully told until now.

In 2021 there were 341 entrants from 48 countries, including 17 from the United States. Entrants must qualify, achieving certain standards such as running 174 miles (men) or 161 miles (women) in 48 hours. Today's course is mostly pavement, but also includes a difficult section at night in the mountains, at about mile 100, on historic goat trails.
