the relay messaging system was one of the most efficient systems implemented by the Incas,
The chaski or messenger runner was the human element used for this purpose, recruited from among the fastest and most athletic young people who did not exceed 20 years of age, they were placed in relief positions distributed throughout the great Inca trail 'QAPACÑAN', many Spanish chroniclers wrote about the great feats of speed and efficiency with which messages were transmitted, it is said that a message could travel 1200 km in just 6 days, the chaskis not only carried messages but could also carry a load of approx 15 kg consisting of some exotic foods that according to the chronicles arrived fresh at the hands of the great lords of Peru.
