Ultra-runners are athletes who participate in races longer than the traditional marathon distance of 26.2 miles. These events can range from 50 kilometers to over 100 miles, often taking place on trails or rugged terrains. Ultra-running challenges both physical endurance and mental resilience, as participants must manage fatigue, hydration, and nutrition over extended periods. Training for ultra-running typically involves long-distance runs, strength training, and recovery strategies. Many ultra-runners also join communities or clubs to share experiences and tips. Notable ultra-running events include the Western States Endurance Run and the Badwater Ultramarathon, which attract competitors from around the world.
