In 1860, a startup called the Pony Express promised something unthinkable: mail from Missouri to California in just 10 days. Riders galloped between about 200 relay stations strung across the prairies, mountains, and deserts of the American West. Each rider rode about 75 miles at full pace, switching to a fresh horse every 10 to 15 miles before handing the mail bag to the next rider.
The riders were typically teenagers - small and light, so the horses could move faster. They carried a special leather pouch called a mochila, which could be tossed onto a fresh horse in seconds at each station. They rode through blizzards, attacks, and exhaustion. Astonishingly, only one mail bag was ever lost across the entire 18 months of operation.
Then the transcontinental telegraph line was completed in October 1861. Suddenly any message could cross the country in seconds, not days, for a fraction of the cost. The Pony Express shut down just two days after the wire opened. Its run was short, but its image of brave young riders chasing the sunset still defines American Western mythology.
