Run A Faster Half Marathon With THIS Workout from The Running Channel is worth your time. Below is a breakdown of the key elements so you can give it a shot today. For complete detail, watch the full video.

Key points

• Three 20-minute blocks make up this 60-minute session, each progressing in intensity. This approach to long intervals develops lactate threshold and aerobic capacity. Want to understand structured workouts more deeply? See our guide on Mastering Interval Training: Science-Backed Workouts and How a Smart App Can Personalize Them.
• First block: run slightly faster than your marathon pace.
• Second block: run a touch slower than your target half‑marathon pace.
• Third block: run quicker than your target half‑marathon pace, building a strong finish.
• Stay moving the whole hour—no walking breaks.
• Adjust block duration (try 10 or 30 minutes) and paces to match your goal. Progressive pacing works across distances. Learn how for the 10K in Mastering the 10K: Proven Training Plans, Pace Strategies, and How a Smart App Can Elevate Your Performance.
• Keep effort within ±3‑5 seconds of target pace; focus on steady breathing and solid form.

Workout example (paces shown as minutes per kilometre; adapt to miles if you prefer):

1. Warm‑up – easy jog ~5 min.
2. Block 1 (20 min) – target ~4:00 /km (quicker than marathon pace). Start controlled, settle into rhythm, and stay within a few seconds of target.
3. Block 2 (20 min) – hold ~3:50 /km (just below goal half‑marathon pace). Maintain steady effort while monitoring heart rate and breathing.
4. Block 3 (20 min) – push to ~3:45 /km (quicker than goal half‑marathon pace). Drive hard while keeping form tight. This block teaches you to finish strong with a negative split—a valuable skill for any distance.

5. Cool‑down – 5‑10 min easy jog, then stretch.

Tip: If your goal pace is different, swap in your numbers. Try three 10‑minute blocks for a shorter session or three 30‑minute blocks for marathon training.

Practical tips

• Start conservatively; don’t rush the early minutes.
• Run with a partner or use a pace app for accountability.
• Stay within 3–5 seconds of each target pace.
• Keep your chest up, knees driving, relaxed breathing—especially important in the final block.
• No walking breaks—this workout demands sustained effort for the full hour.

Closing note Give this 60-minute progressive run a try and adjust the paces in the Pacing app to fit your plan. You’ll feel stronger and more confident, ready to chase that sub‑80‑minute half marathon.
