Studded with 153 stations, the Pony Express trail used 80 riders and between 400 and 500 horses to carry mail from the settled Midwest to the new state of California. Riders could deliver mail in just 10 days, compared to the three weeks traditional stagecoach delivery required. Riders would stop every 16 to 24 kilometers (10 to 15 miles) to hop onto a fresh horse at the four to six relay stations on their leg of the trail.
