An endurance athlete is characterized by their ability to sustain prolonged physical exertion. These athletes excel in sports requiring significant stamina, such as marathon running, cycling, and triathlon. Endurance athletes often engage in rigorous training regimens that focus on improving cardiovascular efficiency, muscular endurance, and mental fortitude. Their performance frequently depends on their aerobic capacity and ability to cope with fatigue over extended periods, differentiating them from athletes competing in short-burst sports.
