A closer look
It sounds impossible, yet armies of messengers once ran across mountains and deserts on nothing but calloused feet — and they often beat horses. How? Empires like the Incan built their territories along narrow stone paths where four-legged animals couldn’t travel. Instead, they trained human runners whose stamina was astonishing. These messengers sprinted in relays, leaping from station to station, carrying knotted cords that told stories of tribute, war, or coronations. A royal message could cross hundreds of miles in just a few days. It was a living internet on two legs, powered by lungs of iron and feet like leather.
