600m Run

The 600m run is a middle-distance conditioning effort. It trains your stamina, pacing judgment, and ability to hold a hard but sustainable speed. You have to run faster than a jog, but slow enough that you don't blow up before the finish.

Start on a track, measured route, treadmill, or any flat, safe surface. Stand tall with your feet under your hips, shoulders relaxed, and eyes looking forward. Let your arms hang loosely at your sides.

Begin with short, quick strides and build to your target pace within the first 50 to 100 meters. Keep your torso upright, land with your feet under your body, and drive your arms forward and back without crossing them over your chest. Hold your pace steady through the middle, then push the last 100 meters.

Breathe in a rhythm you can maintain - usually through your nose and mouth together - and keep your core gently braced so you don't collapse at the waist. To make it easier, break it into shorter intervals with rest, or slow the pace. To make it harder, pick up the pace or add a slight incline.

Fault: Going out too fast and then fading. Fix: Start controlled and negative-split the effort by running the second half slightly faster than the first.

Fault: Overstriding and slamming your heels into the ground. Fix: Take shorter, quicker steps and land with your foot under your hips instead of far out in front.

Fault: Tensing the shoulders or letting arms cross the chest. Fix: Shake out your hands every so often and keep your arms swinging forward and back, not across your body.

Fault: Leaning back or sitting into your hips as you fatigue. Fix: Reset your posture by standing taller and leaning slightly forward from the ankles, not the waist.
