Speed work is a type of training designed to improve a runner's speed and efficiency. It typically involves short, intense bursts of running, such as sprints or intervals, followed by periods of rest or slower-paced running. This method helps to build strength, increase cardiovascular fitness, and enhance overall performance. Incorporating speed work into a training plan can benefit runners of all levels, from beginners to seasoned athletes. Common forms of speed work include interval training, fartlek, and tempo runs. These workouts not only help improve race times but also make running more enjoyable by adding variety to the routine.
