How to Properly Stretch Before Running

A proper preparation routine before running is designed to increase core body temperature, activate the specific muscles used in the running stride, and prepare the body’s systems for the impact and demands of the activity. This preparation ensures that the muscles and joints are pliable and ready to perform efficiently from the first step, rather than relying on the initial miles of a run to serve as a warm-up. Understanding the correct method for this pre-run preparation is essential for anyone looking to build a sustainable running practice.

Understanding Dynamic Warm-ups Versus Static Stretching

The preparation methods used before a run fall into two main categories, and understanding the difference between them is fundamental to establishing a proper routine. Static stretching involves holding a muscle in a lengthened position, typically for 30 seconds or longer, and is primarily aimed at improving long-term flexibility and range of motion. Research indicates that performing these long-hold stretches on cold muscles before a workout can temporarily decrease muscle power and force production. The extended lengthening may trigger a neurological response that essentially “turns off” the muscle, making it less responsive and potentially increasing the risk of muscle strain or injury during the run.

Dynamic warm-ups, by contrast, consist of continuous, controlled movements that take the joints and muscles through a full range of motion, often mimicking the action of running. The goal of this movement-based approach is to gradually increase blood flow, heart rate, and muscle temperature, preparing the body for the activity. This method activates the nervous system and improves the elasticity of the muscle-tendon unit without reducing muscle stiffness to a point that would compromise performance. Dynamic movement is the established standard for pre-run preparation, while static stretching is best reserved for the cool-down period after a run.

Step-by-Step Guide to the Pre-Run Routine

A complete pre-run routine is structured in phases, moving from general light movement to more specific, running-focused drills. The preparation should begin with a phase of light cardio to gently elevate the heart rate and begin warming the muscles. This can be accomplished with approximately five minutes of easy walking or a very slow jog, allowing the body to transition out of a resting state. This initial movement ensures that the muscles are receptive to the more targeted dynamic exercises that follow.

The second phase introduces specific dynamic movements designed to activate the major muscle groups used in running. These movements should be performed with control and fluidity, focusing on a full but comfortable range of motion, often covering a distance of 10 to 20 yards or completing 10 to 12 repetitions per side.

Walking lunges are an excellent movement that targets the glutes, quadriceps, and hip flexors, requiring a large step forward and dropping the back knee toward the ground while maintaining an upright torso. High knees and butt kicks are two drills that increase hip flexor and hamstring activation, respectively, by focusing on quick, exaggerated movements of the lower leg.

Dynamic Movement Examples

  • Leg swings: Performed both forward/backward and side-to-side, these mobilize the hip joint and lengthen the hamstrings and hip flexors. The forward swing should move freely toward the opposite hand.
  • “Frankenstein” walks: Walk forward while raising one leg straight out and reaching for the toes with the opposite hand, actively stretching the hamstrings.
  • Controlled hip circles: Lift the knee and rotate it outward as if stepping over a low hurdle to mobilize the hips.
  • Ankle circles: Perform circles while standing or lying down to address the often-overlooked ankle joint, ensuring the lower leg is prepared for ground impact.

Crucial Timing and Common Warm-up Errors

The total time dedicated to the proper pre-run routine should generally fall within a 10-to-15-minute window, balancing preparation with not inducing fatigue before the run.

The timing of the routine relative to the start of the run is crucial. The warm-up is most effective when performed immediately before the run, ideally within five to ten minutes of starting the activity. If a significant gap occurs between the end of the warm-up and the start of the run, the body temperature and muscle activation begin to decline, and the beneficial effects are lost.

A common mistake is performing the warm-up too early, such as 30 to 45 minutes before a race, which allows the body to cool down and the muscles to lose their primed state. Another frequent error is skipping the routine entirely, believing the first mile is sufficient preparation, which can put unnecessary stress on cold tissues. Runners should also avoid stretching too aggressively or trying to push through sharp or existing pain, as the goal is gentle preparation, not intense flexibility gains.
