Endurance sport is a family of athletic disciplines that prioritize prolonged, steady physical effort over extended periods. Activities in this category test aerobic capacity, muscular endurance, pacing, and resilience, typically requiring minutes to many hours of continuous or repeated exertion.

Common formats include distance running (marathons and ultramarathons), road cycling, open-water and pool swimming over long distances, cross-country and adventure racing, and multi-sport events such as triathlons and duathlons. Ultramarathons extend beyond the traditional marathon distance of 42.195 kilometers, and can range from 50 kilometers to multi-day races.

Physiology and training focus on sustaining energy production through aerobic metabolism, managing fatigue, and delaying metabolic byproducts. Athletes develop high aerobic power, efficient movement economy, and fatigue resistance. Training often uses periodization, long steady-state sessions, tempo efforts, high-volume mileage, and race-specific simulations, along with nutrition and hydration strategies during events.

Competition is governed by multiple federations depending on the sport, with Olympic disciplines including track and road running, cycling, swimming, and triathlon. Ultramarathon and multi-day endurance events have specialized organizations and race series worldwide. Safety considerations emphasize gradual progression, heat and cold management, injury prevention, sleep and recovery, and medical monitoring during events lasting many hours.

Endurance sport has a global following and is characterized by personal time trials, record attempts, and community-supported events that promote conditioning, discipline, and mental endurance as integral components of performance.
