noun
Usage
What is a marathoner? A marathoner is someone who competes in or completes a marathon, a 26. 22-mile (42. 2-kilometer) long-distance race. Marathons are most commonly running races, and marathoners are perhaps most commonly called marathon runners. But some marathoners complete marathons in wheelchairs. The word marathoner can be applied to any participant in a marathon but is especially used to refer to a person who regularly competes in marathons. The term ultramarathon refers to a race of 50 miles or more, and the superhumans who compete in these can be called ultramarathoners. The word marathon is also often used in a more general way to refer to a contest or event that takes a particularly long time and requires endurance, such as a dance marathon, or in a more figurative way to refer to a task or undertaking that takes a long time and requires patience. But the word marathoner isn’t commonly used in these contexts—it’s typically reserved for a racer in a literal marathon. Example: I’ve always wanted to run a marathon, so I started training as a marathoner today.
