long slow distance running

Long Slow Distance (LSD) running is a training method that involves running at a steady, moderate pace for an extended period, typically longer than your usual runs. The goal is to build endurance, improve aerobic capacity, and increase the body's ability to burn fat for fuel. It emphasizes maintaining a comfortable speed where conversation is possible, minimizing fatigue and injury. This type of training is commonly used by marathoners and endurance athletes to develop a strong, efficient cardiovascular system, ensuring they can sustain longer distances with consistent effort.
