Intro: Got inspired by The Running Channel’s THIS Is What a 5k PB Looks Like? The video’s worth your time. Here’s how to run the workout yourself.
Key Points:
- Master the negative-split strategy: start controlled, then accelerate kilometer by kilometer
- Keep the first kilometer easy and focus on smooth breathing, relaxed shoulders
- On short climbs, hold your effort steady – the downhill gives you free time back
- Check the Stamina gauge (Garmin watch) to track your effort; start around 100% and let it drop toward the finish
- Form matters: look ahead, stand tall, open your shoulders, drive through your arms
Workout Example (5K Negative Split):
| Km | Target Pace (min:sec per km) |
|---|---|
| 1 | 4:45 |
| 2 | 4:40 |
| 3 | 4:35 |
| 4 | 4:30 |
| 5 | 4:25 |
- Short hill (≈100 m): keep effort constant; ignore the watch.
- Cool‑down: 5–10 minutes easy, focusing on relaxed breathing.
Practical Tips to Try Right Now:
- Next 5K, target a 4:45/km first kilometer and pick up the pace each segment
- When a short hill appears, hold your effort steady and let the descent return the favor
- Use a Stamina gauge on your Garmin – if it’s above 80% at the 3 km mark, you’re in good shape
- Head level, shoulders loose, pump your arms to keep your posture tall and efficient
Closing Note: Test the negative-split approach on your next 5K and adjust the paces using the Pacing app to fit your current fitness. You’ll discover how a properly structured effort pays off—and earn a new PB in the process. 🎉
