Intro

Based on “Can We Beat Our Best 5k Times In 10 Weeks?” from The Running Channel. The video has practical tactics. We’ve pulled out the essentials so you can start training differently today. Watch the full video for more.

Key points

• Start slow. Most runners torpedo a 5K by hammering the first kilometre. Hold back for 1-2 km, find a comfortable rhythm, then build up.
• Even or negative pacing. Hold a steady effort or run the second half a few seconds quicker. Anything beats fading at the end.
• Mantra and focus. A short phrase repeated every few strides anchors your form and breathing in the last kilometre.
• 10-week push. Set a realistic goal time, run a baseline 5K now, and track your weekly improvement.

Workout example

5K pace-control interval (a flat loop or park course works best):

1. Warm-up: 10 min easy jog and dynamic stretches.
2. First 2 km: 30-45 seconds slower than your goal 5K pace (e.g. 4:30/km if your target is 4:00). Breathe easy.
3. Next 2 km: at goal pace (4:00/km). Steady cadence without straining.
4. Final 1 km: aim for a negative split, 3:55/km or a touch quicker.
5. Cool-down: 5-10 min easy jog.

Tip: a GPS watch or the Pacing app lets you lock in the exact paces with live feedback.

Closing note

Try this pacing approach on your next 5K. Adjust splits to your goal pace in the Pacing app. Hold back early.
