If you’re training for a marathon, incorporating tempo runs into your weekly schedule can be a game changer. These workouts develop your ability to sustain a challenging pace, improve your lactate threshold, and build the mental toughness necessary to power through the final miles of a marathon.
What Is a Tempo Run?
A tempo run is a sustained effort at a “comfortably hard” pace—fast enough to push your limits but not so intense that you’re gasping for air. Think of it as running at a pace where speaking in short phrases is possible, but full conversation? Not a chance.
This pace typically hovers just below your lactate threshold—the intensity level where your body begins accumulating lactic acid faster than it can clear it. Training near this point helps your body adapt to longer, faster efforts without succumbing to fatigue too soon.
Understanding the Lactate Threshold
Your lactate threshold is one of the most crucial markers in endurance training. It’s the point at which lactate starts building up in your blood during exercise. Once you cross that line, your performance can decline rapidly due to muscular fatigue.
Training just under this threshold increases your body’s ability to flush out lactic acid efficiently, enabling you to run longer at higher intensities—vital for any marathon runner aiming to hit a personal best.
Tempo Run vs. Threshold Run: What’s the Difference?
While both terms are often used interchangeably, there’s a subtle but important distinction:
– Threshold Runs are more structured and rely on specific numbers instead of just how you feel. They use tools like heart rate monitors or pace calculators to make sure you’re training at just the right effort level—right below the point where your muscles start to build up too much lactic acid.
Some runners go to a sports lab for testing, where experts help find their lactate threshold (the intensity where fatigue starts to build fast). But you can also estimate it yourself using a good heart rate monitor or running app. This helps you stay in the ideal training zone, so your workouts are more effective and less likely to lead to burnout or injury.
– Tempo Runs, on the other hand, are more intuitive. They’re based on perceived effort—pushing yourself at a “comfortably hard” pace—without needing lab data or gadgets. While still targeting a similar training zone, tempo runs allow for more flexibility, making them a popular choice for runners of all levels.
Key Benefits of Tempo Runs for Marathon Runners
Incorporating tempo runs into your training delivers several powerful advantages:
– Elevated Lactate Threshold: Helps you sustain faster paces for longer without fading.
– Mental Fortitude: Prepares you mentally to push through tough spots during the race.
– Improved Cardiovascular Efficiency: Trains your heart and lungs to perform optimally under stress.
– Enhanced Running Economy: Teaches your body to conserve energy and delay fatigue during long-distance events.
How to Structure a Tempo Run
1. Continuous Tempo Run
– Duration: 20–45 minutes
– Pace: “Comfortably hard” – around 85–90% of your max heart rate
– Goal: Build sustained endurance and mental grit
This is the classic tempo run format. Warm up, settle into your tempo pace, and hold it for the prescribed duration before cooling down.
2. Tempo Intervals
– Example Workout: 3 x 10 minutes at tempo pace with 2–3 minutes of easy jogging recovery
– Goal: Develop speed-endurance while managing fatigue
This variation allows you to break the effort into manageable chunks, making it easier for newer runners or as a progression toward longer continuous runs.
Tempo Run Workouts by Experience Level
Beginner
– Warm-up: 10 min easy jog
– Main Set: 2 x 10 minutes at tempo pace (3 min recovery jog)
– Cool-down: 10 min easy jog
Intermediate
– Warm-up: 10 min easy jog
– Main Set: 3 x 15 minutes at tempo pace (2 min recovery)
– Cool-down: 10 min easy jog
Advanced
– Warm-up: 15 min easy jog
– Main Set: 40 minutes continuous at tempo pace
– Cool-down: 15 min easy jog
Pro Tips for Maximizing Tempo Runs
– Ease into it: Start with shorter efforts and build up duration and intensity gradually.
– Find your pace: Use perceived effort, a pace calculator, or heart rate monitor to dial in your ideal tempo pace.
– Vary your workouts: Rotate between continuous and interval-style tempo runs to avoid plateaus.
– Recovery matters: Space out hard sessions to avoid overtraining and maximize gains.
Final Thoughts: Make Tempo Runs Your Marathon Secret Weapon
Tempo runs are more than just another training session—they’re a cornerstone of effective marathon preparation. By training your body to perform near the lactate threshold, you’ll improve speed, efficiency, and mental stamina—three critical ingredients for a successful marathon.
Whether you’re just beginning your marathon journey or aiming for a PR, mastering the art of the tempo run can take your performance to the next level.
