What Is My Tempo Pace?

The concept of “tempo pace” in running is often discussed, but its precise definition and application can be elusive. For runners, understanding and accurately identifying tempo pace is crucial for unlocking significant improvements in aerobic capacity, lactate threshold, and overall race performance. This article delves into the nuances of tempo pace, providing a comprehensive guide to help you define, measure, and effectively integrate it into your training regimen.

Defining Tempo Pace

At its core, tempo pace refers to a comfortably hard effort level that can be sustained for a significant duration, typically between 20 to 40 minutes in a single session. It sits between your easy aerobic running pace and your hard interval or race pace. The key characteristic of tempo running is its ability to push your lactate threshold – the point at which lactate begins to accumulate in your blood faster than your body can clear it – outwards, allowing you to sustain a faster pace for longer before fatigue sets in.

The Lactate Threshold Connection

Understanding your lactate threshold is fundamental to grasping tempo pace. During moderate-intensity exercise, your body produces lactate as a byproduct of anaerobic metabolism. As you increase your intensity, lactate production rises. However, your body can clear this lactate up to a certain point. Your lactate threshold is the highest intensity at which your body can still clear lactate as effectively as it’s being produced.

Tempo running specifically targets this threshold. By running at an intensity that is challenging but sustainable, you train your body to become more efficient at clearing lactate. This means that in a race or harder workout, you can run at a higher intensity before reaching that uncomfortable “wall” of lactic acid buildup.

Perceived Exertion vs. Heart Rate vs. Pace

Defining tempo pace can be approached through several metrics:

• Perceived Exertion (RPE): This is often the most accessible and practical method. On a scale of 1 to 10, tempo pace typically falls between a 6 and an 8. You should be able to speak in short, broken sentences, but not carry on a full conversation. You’ll feel a distinct effort, with increased breathing and heart rate, but you should feel in control and able to maintain the effort. Some runners describe it as a “comfortably hard” or “moderately hard” pace.

• Heart Rate Zones: For those who monitor their heart rate, tempo pace generally corresponds to Zone 3 or the lower end of Zone 4. This typically translates to 80-90% of your maximum heart rate. However, it’s important to note that heart rate can be influenced by various factors such as fatigue, hydration, and ambient temperature, so it should be used as a guideline rather than a strict rule.

• Pace (in minutes per mile or kilometer): This is the most objective measure but requires a good understanding of your current fitness. Tempo pace is usually 15-30 seconds per mile (or 10-20 seconds per kilometer) slower than your current 5k race pace, or about 10-20 seconds per mile faster than your comfortable long-run pace. The exact pace will vary significantly from runner to runner based on their training history, genetics, and current fitness level.

Identifying Your Tempo Pace

The most effective way to determine your tempo pace is through a combination of understanding these metrics and engaging in personalized testing.

The Threshold Run Test

A practical way to find your tempo pace is to conduct a threshold run. Here’s how:

1. Warm-up: Begin with 10-15 minutes of easy jogging to prepare your body.
2. Tempo Segment: Run for 20-30 minutes at what feels like a comfortably hard effort. Focus on maintaining a steady pace where you can speak in short phrases. Pay close attention to your breathing and perceived exertion.
3. Cool-down: Finish with 10-15 minutes of easy jogging.

During the tempo segment, try to gauge your RPE, monitor your heart rate (if possible), and note the pace you’re running. The average pace you maintained during this 20-30 minute segment is a good approximation of your current tempo pace.

Using Race Performances as Benchmarks

Your recent race performances can provide valuable insights into your tempo pace.

• 5k Race Pace: As mentioned, your tempo pace is typically 15-30 seconds per mile slower than your 5k pace. If you recently ran a 5k, use that pace as a starting point. For example, if your 5k pace is 7:00/mile, your tempo pace might be around 7:15-7:30/mile.

• 10k Race Pace: Tempo pace is also often close to your 10k race pace, perhaps slightly slower. If your 10k pace is 8:00/mile, your tempo pace might be around 8:00-8:15/mile.

• Half Marathon or Marathon Pace: These paces are significantly slower than tempo pace and are more indicative of your easy or long-run pace.

Online Calculators and Training Apps

Many online running calculators and training apps can help estimate your tempo pace based on your recent race results or current training data. These tools often use algorithms that take into account various physiological factors to provide a personalized pace recommendation. While useful, these should be used as a starting point and adjusted based on your actual feel during a run.

Integrating Tempo Pace into Your Training

Once you have identified your tempo pace, the next step is to strategically incorporate it into your training plan to maximize its benefits.

Types of Tempo Workouts

Tempo running isn’t a one-size-fits-all workout. There are variations that can be used to target different aspects of your fitness:

• Continuous Tempo Runs: This is the most common form, where you run for a sustained period (20-40 minutes) at your tempo pace without breaks. These are excellent for building endurance and raising your lactate threshold.

• Lactate Threshold Intervals: These involve shorter, faster intervals at or slightly above your tempo pace, interspersed with short recovery periods. For example, 3-5 repetitions of 8-10 minutes at tempo pace with 1-2 minutes of easy jogging in between. These workouts are more demanding and can help sharpen your speed at and slightly above your lactate threshold.

• Cruise Intervals: Similar to lactate threshold intervals but with slightly longer work periods and shorter recovery. For instance, 2-3 repetitions of 15-20 minutes at tempo pace with 3-5 minutes of easy jogging. These offer a good balance of sustained effort and recovery.

Training Frequency and Progression

• Frequency: For most runners aiming to improve their tempo pace, one tempo workout per week is sufficient. This allows for adequate recovery between hard sessions. Beginners might start with one tempo session every 7-10 days.

• Progression: As your fitness improves, you can progress your tempo workouts in a few ways:

  • Increase Duration: Gradually extend the length of your continuous tempo runs by 5 minutes each week or two.
  • Increase Pace: If you consistently feel your current tempo pace is becoming too easy, you can shave off a few seconds per mile.
  • Increase Intensity of Intervals: For interval sessions, you can increase the length of the intervals, decrease the recovery time, or slightly increase the pace.
  • Increase Volume: Add an extra interval or extend the duration of your total tempo volume within a workout.

Periodization and Seasonal Planning

Tempo running is a cornerstone of a well-rounded training plan. It’s particularly important during periods focused on building strength and speed endurance, typically in the build-up phase leading to a race.

• Base Building: During base building, the focus is on aerobic development with predominantly easy running. Tempo work can be introduced gradually once a solid aerobic foundation is established.

• Pre-Competition Phase: This is where tempo workouts are most crucial. They help fine-tune your body to sustain faster paces for longer, preparing you for race-day efforts.

• Tapering: In the week or two leading up to a race, tempo workouts should be reduced in volume and intensity to allow for full recovery and freshness on race day. A short, sharp tempo effort might be included a few days before the race to keep your legs feeling sharp.

Benefits of Tempo Pace Training

Consistent tempo pace training yields a multitude of benefits for runners of all levels:

• Improved Lactate Threshold: This is the primary benefit, allowing you to run faster for longer before fatigue sets in.
• Enhanced Aerobic Capacity: Tempo runs push your cardiovascular system to become more efficient at delivering oxygen to your muscles.
• Increased Running Economy: Your body becomes more economical at using energy at higher intensities.
• Mental Toughness: Sustaining a comfortably hard effort builds mental resilience and the ability to push through discomfort.
• Race Specificity: Tempo pace is very close to goal race paces for many distances (e.g., 10k to half marathon), making it highly specific for performance improvement.
• Injury Prevention: When incorporated correctly and with proper progression, tempo running can strengthen muscles and connective tissues, contributing to injury prevention.

By understanding what your tempo pace is and how to train it effectively, you are taking a significant step towards unlocking your full running potential. It’s a powerful tool that, when wielded wisely, can transform your performance and your relationship with challenging running efforts.
