Key Workouts for Half Marathon Success

The half marathon demands a mix of speed, strength and endurance. To train effectively you need more than just long runs or intervals. You need a well-rounded set of workouts that target every aspect of performance. This post brings together ten essential sessions designed to build control, improve pacing and prepare you to run your best on race day.

What Are the Key Workouts for a Half Marathon?

The half marathon isn’t just a test of endurance. It’s a strategic challenge that demands controlled speed, stamina and mental focus over 13.1 miles. Simply running more miles won’t get you to the finish line faster. To race well, you need sessions that push your threshold, refine your pacing and condition your body to stay strong when fatigue kicks in.

These 10 sessions are carefully selected to target exactly that.

Half Marathon Run Training Zones

Heart rate and RPE (Rate of Perceived Exertion) are simple but powerful tools to guide your training. Heart rate measures how fast your heart is beating during exercise, showing how hard your body is working. RPE is how hard you feel you're working on a scale, usually from 1 to 10. Together, they help you understand your effort level, manage training intensity and avoid overtraining. By paying attention to heart rate and RPE, you can train smarter, improve performance and reduce injury risk.

  • Zone 1 (Recovery): 68–73% max HR / RPE 1–2 — very easy jog

  • Zone 2 (Endurance): 73–80% max HR / RPE 3–4 — easy aerobic running

  • Zone 3 (Tempo): 80–87% max HR / RPE 5–6 — steady, strong effort

  • Zone 4 (Threshold): 87–93% max HR / RPE 7–8— comfortably hard

  • Zone 5 (VO2 Max): 93–100% max HR / RPE 9-10 — short, intense reps
