Evidence-based strategies for your 5K running warm-up

A structured approach to preparing your body for optimal performance and reducing injury risk before a 5K run.

The purpose of a pre-run warm-up

I see many runners in Brussels start their 5K runs the moment they hit the path. It feels efficient. But research shows a short warm-up helps you perform better and protects your muscles. The goal is straightforward. You want to raise your body temperature, get blood flowing to your legs, and wake up your nervous system for the effort ahead.

Moving from static to dynamic

Old habits like static stretching—holding a stretch while standing still—can actually be counterproductive before a run. Static stretching may reduce the power output of your muscles, which is the opposite of what you need for a 5K. Instead, we focus on dynamic movements. These movements mimic the mechanics of running and keep your joints moving through their full range of motion while the muscles are actively engaged.

A solid 10 to 15-minute warm-up should transition you gradually from your resting state to your race pace. Start with light activity and move into specific movements that target the hips, knees, and ankles.

Recommended warm-up sequence

Follow this sequence to ensure you are ready for your 5K effort:

Five minutes of easy, conversational-pace jogging to elevate your heart rate.
Leg swings (front-to-back and side-to-side) to improve hip mobility.
Walking lunges with a torso twist to activate the glutes and core.
High knees and butt kicks to stimulate the neuromuscular pathways required for your running cadence.
Two or three short accelerations or 'strides' over 50 meters, gradually building up to your goal 5K pace.

The importance of gradual progression

The key takeaway is that your warm-up should build intensity in parallel with your heart rate. If you jump straight into race pace, your body is effectively 'cold', which forces a sudden, high-stress demand on your cardiovascular and muscular systems. By using the dynamic movements listed above, you ensure that your body is physically and mentally ready to handle the load of the full 5K session from the very first meter.

Note: If you are training in cold weather conditions, extend the initial light jog by a few minutes to ensure your muscles are sufficiently warm before starting the more explosive dynamic movements.

Take action this week

Before your next 5K training session, commit to performing this specific sequence. Notice how your legs feel during the first kilometer compared to when you skip the warm-up.
