What happened
Along the road network the Inca built two tiers of rest stops: small stations called chaskiwasi spaced roughly every 20 kilometers where ordinary travelers could shelter, and larger, more elaborate complexes called tambos serving as administrative and supply centers. Messages moved through a relay system of runners called chasquis, who World History Encyclopedia describes as operating in short bursts, handing information to a fresh runner stationed every six to nine kilometers so the message never slowed for one person's endurance. Using this method, information, and even perishable goods like fresh fish or seafood destined for Inca nobles' tables, could travel up to 240 kilometers in a single day. Because messages passed through many hands and oral retellings, runners likely carried quipu cords alongside their spoken message as a memory aid to help preserve its exact content.
Why it matters
This relay system gave Cuzco something close to same-day awareness of events at the empire's frontiers, a communication speed that had no equivalent elsewhere in the pre-industrial Americas. It also explains how a lightly staffed administration could coordinate tribute, troop movements, and food distribution across a territory 5,500 kilometers long without a postal service in the European sense.
How we know
Details of the relay distances and speeds come from World History Encyclopedia's account of the road system, drawing on Spanish colonial descriptions of a system that was still partly functioning when the conquistadors arrived and could observe it firsthand.
