Competing in a MARATHON is an endurance event that requires months of training and preparation. It involves running a long-distance race, usually over 26 miles, and is a popular challenge for athletes and recreational runners alike. The term 'MARATHON' comes from the legend of Pheidippides, a Greek soldier who ran from the town of MARATHON to Athens to deliver news of a military victory. To compete in a MARATHON, one must have the physical and mental strength to complete the race.
