“Run A Faster Half Marathon With THIS Workout” from The Running Channel is worth your time. Below is a breakdown so you can give it a shot today. Watch the full video for complete detail.

Key points

• Three 20-minute blocks make up this 60-minute session, each progressing in intensity. This builds lactate threshold and aerobic capacity. For more on session design, see Mastering Interval Training: Science-Backed Workouts and How a Smart App Can Personalize Them.
• First block: slightly faster than marathon pace.
• Second block: a touch slower than target half-marathon pace.
• Third block: quicker than target half-marathon pace.
• Stay moving the whole hour. No walking breaks.
• Adjust block duration (10 or 30 minutes) and paces to match your goal. Progressive pacing works across distances. For the 10K, see 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.
3. Block 2 (20 min): hold ~3:50/km (just below goal half-marathon pace). Maintain steady effort.
4. Block 3 (20 min): push to ~3:45/km (quicker than goal half-marathon pace). Drive hard while keeping form. For more speed work, see Mastering 5K Speed: Proven Interval Strategies to Cut Minutes off Your Time.
5. Cool-down: 5–10 min easy jog, then stretch.

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.
• No walking breaks.
