Half Marathon Training: 10 Tempo Sessions
SUMMARY
Tempo training for the half marathon sits in Zone 3 — around 80–87% of max heart rate and RPE 5–6 and plays a vital role in building race-day endurance. These steady, controlled sessions strengthen your aerobic base, improve pacing efficiency and help you maintain speed deep into the final miles. The 10 workouts in this post are designed to sharpen your focus, develop fatigue resistance and make your half marathon pace feel smooth and sustainable.
What Is a Tempo Run in Half Marathon Training?
The half marathon is a true test of endurance, speed, and race strategy. Tempo runs are one of the most effective ways to improve your ability to sustain pace, build strength, and finish strong on race day. Tempo workouts are typically run in Zone 3 — a controlled, steady effort that challenges your aerobic system without tipping into threshold.
These runs train your body to stay efficient over long distances, manage fatigue, and build the mental focus needed for the second half of the race. They’re especially valuable in half marathon training because they prepare you to run hard — but smart — across the full 13.1 miles.
In this post, you’ll find 10 tempo run sessions designed to boost endurance, improve pacing, and build the strength to finish your next half marathon with control and confidence.
Metrics for Half Marathon Tempo Training
Tempo efforts in half marathon prep are about sustaining strong aerobic effort just below threshold — long enough to build speed endurance without overreaching.
Heart Rate: 80–87% of your max heart rate (Zone 3)
RPE (Perceived Effort): 5–6 out of 10 — comfortably hard
How It Feels: Controlled breathing, steady rhythm. You can speak in short phrases, but anything more feels challenging.

Mini FAQ: Tempo Sessions
What is a tempo run for half marathon training?
A tempo run for the half marathon is a steady, sustained effort close to your half marathon race pace. It’s designed to improve stamina, aerobic strength, and pacing control — running “comfortably hard” but not all-out.
How fast should I run my half marathon tempo sessions?
Aim for your half marathon goal pace. If running by effort, it should feel like a 7–8 out of 10, where you are working but still fully in control and sustainable.
How long should a tempo run be for half marathon prep?
Tempo sessions typically include 20 to 45 minutes of continuous running, or structured intervals like 2 x 15 minutes at tempo pace with short recoveries. These build your ability to sustain race effort longer.
How often should I schedule tempo sessions?
Include one tempo workout per week during your key half marathon training phase. As race day approaches, some sessions may extend to longer tempo efforts to simulate race conditions.
Are tempo sessions different from threshold workouts?
Yes — slightly. Threshold runs target the lactate threshold specifically (your maximum sustainable hard pace), while half marathon tempo runs are a little easier and a little longer — closer to your actual race pace and focused on endurance rather than pure threshold development.
Final Thoughts!
Tempo training is one of the most effective ways to improve your half marathon performance. Incorporating one or two of these workouts into your training plan each week will help you build endurance, increase speed, and develop a smart race strategy.
Stay consistent, trust your training, and get ready to crush your next half marathon!
