8.82 km Walk-Run Interval Training: Finishing Stronger with Every Run

Today’s training session focused on controlled interval work, combining walking recoveries with progressively faster running efforts. The goal was simple: maintain good form, recover effectively and finish stronger than the session began.

Workout Summary

• Total distance: 8.82 km
• Workout: Walk 1 km / Run 1 km × 3
• Cooldown: 2.82 km walk
• Average pace: 8:07 per km
• Average heart rate: 111 bpm
• Maximum heart rate: 172 bpm
• Calories burned: 680 kcal

How the Session Progressed

The walking sections allowed my heart rate to recover before each running effort. Instead of slowing down as fatigue built, every running interval became faster.

• Run 1: 5:02/km
• Run 2: 4:48/km
• Run 3: 4:44/km

Progressively faster intervals are a positive sign that pacing was well managed and there was enough energy left to finish strongly.

Heart Rate Analysis

The average heart rate remained relatively low because of the walking recovery periods, while the maximum heart rate of 172 bpm showed that the running intervals still provided a high-intensity stimulus.

Training across multiple heart rate zones helps improve endurance while also developing speed and cardiovascular fitness.

Key Takeaways

• Consistent pacing is often more effective than starting too fast.
• Recovery periods allow higher-quality running intervals.
• Finishing stronger than you start is a good indicator of controlled effort.
• Structured interval training develops both endurance and speed.

Looking Ahead

Sessions like this provide an excellent foundation for improving 5K and 10K performance while building confidence for longer races. The focus will remain on maintaining consistency, gradually increasing fitness and continuing to finish each workout with strength.

Every run is another step towards becoming faster, fitter and more resilient.
