Quick Summary

Here’s a breakdown of Training to Run Negative Splits | The Best Way to Race a Half Marathon from The Running Channel—well worth watching in full. We’ve distilled the key takeaways so you can implement this session right away.

Key Points

• Negative splits: running the second half of a race faster than the first half. It demonstrates both good aerobic fitness and smart pacing.
• Pacing strategy: target roughly 5 seconds per km variation around your goal pace (for instance, 5:45 /km in the first half, then pick it up).
• Tips: 1️⃣ Lock in your target paces, 2️⃣ Use recovery jogs to bring your heart rate down and keep your legs engaged, 3️⃣ Maintain an upright frame and steady cadence to prevent over-striding.

Workout Example (paces in minutes per kilometer, distances in kilometers):

1. Warm-up – 3 km at easy effort.
2. Main set – 5 km at 5:45 /km (steady half-marathon pace).
3. Intervals – 8 × 400 m at 4:55 /km (≈ 4 min 55 sec per km) with 60-second jog recoveries between reps.
4. Progressive finish:
   • 5 km at 5:30 /km.
   • 6 km at 5:25 /km (or faster).
5. Cool-down – 3 km at easy effort.

Practical Tips

• Wear a watch with lap-pace notifications to stay locked onto your splits.
• During recovery segments, keep moving gently to drop your heart rate and avoid stiffening up.
• Hold an upright posture and aim for a cadence around 180 steps/min to stay efficient and avoid overreaching.
• Picture yourself running the race: start controlled, then gradually open it up—this mindset shift helps you move past others when it counts most.

Closing Note

Test this workout and adjust the paces to fit your goal times in the Pacing app. You’ll develop both the fitness and the mental strength to execute negative splits when it matters. Have a great run!
