Well-trained messengers or soldiers: Could manage up to 25–30 miles (40–48 km) per day when necessary, especially on decent roads like those connecting major city-states.
With Pack Animals or Carts:
Average: 10 to 15 miles (16 to 24 km) per day. Roads could be rough or hilly, which slowed progress, and carts especially had trouble in more mountainous regions.
Mounted Couriers or Elite Riders:
Average: 30 to 50 miles (48 to 80 km) per day. Relay systems, as used by the Persians and later emulated, could push these distances even farther—but that was less common in Greek states.
