Strides are short bursts of faster running with recovery in between. They are typically 50 to 150 meters (or 15 to 30 seconds) of running at speeds ranging from 5k to mile race pace. Strides are also known as striders, stride-outs, or accelerations. They are a staple of almost every high school, university, and professional running team, and are a fundamental building block of speed and coordination. Strides are not a full-out sprint, but rather a gradual increase in speed with a focus on maintaining good running form. The goal of strides is to improve running economy, with a focus on turnover and form, and to prepare for faster speeds. They can be included in a warm-up or cool-down, tacked onto an easy run, or run as part of (or all) of a workout. Strides can help improve running balance and form, prevent injuries, and build running speed. They are a safe way of introducing a little speedwork into a training routine with the added advantage of not putting the same stress on the body as high-intensity training sessions.
