What Is A Tempo Run? + Why You Should Add Them To Your Training

Improve your running performance with these threshold sessions.

Tempo runs or threshold runs are a type of workout every runner should include in their training program to improve performance.

Tempo training is moderate-to-hard intensity running designed to make you a faster and stronger runner. Running at a sustained, hard effort will increase your tolerance to run for longer periods of time and longer distances at an “uncomfortable” pace.

Practicing a tempo effort will provide physical benefits and help with mental toughness when facing race day, whether a 5k, 10k, half, or full marathon.

They’re a staple of established endurance athletes across the globe.

In this guide, we will discuss:

What Is A Tempo Run?

A tempo run is a moderate-to-hard intensity training run between 5km and 8km or between 20 minutes and 40 minutes in duration.

The intensity of this sustained effort training run should be around 6 out of 10 in terms of the rate of perceived exertion (we cover exact timings and pace later).

In addition to interval training, a tempo run is an example of a high-quality speed workout for runners and is an essential part of the weekly training plan.

It is widely regarded that the level of effort and the most appropriate pace is when your body switches from using oxygen (aerobic) to without oxygen (anaerobic).

Experienced and elite marathon runners will use longer tempos of up to 20km as an integral part of their preparation.

For instance, elite Kenyan athletes, such as Eliud Kipchoge, ensure that they include at least one tempo run a week in their training plan throughout the year.

In fact, a recent study from the 2020 European Journal of Sport Science comparing the training schedules of Kenyan and Spanish elite athletes highlighted the importance of tempos for Kenyan athletes, with the usual duration per week running at a tempo pace between 45-70 minutes.1Casado, A., Hanley, B., & Ruiz-Pérez, L. M. (2019). Deliberate Practice in Training Differentiates the Best Kenyan and Spanish Long-Distance Runners. European Journal of Sport Science, 1–25. https://doi.org/10.1080/17461391.2019.1694077

Tempo runs help build your lactate threshold pace (LT), which is critical for running faster.

Your LT is the point at which lactic begins to accumulate in muscles. A buildup of this lactic acid in the muscles leads to the fatigue, burning sensation, and soreness that runners experience when running hard.

If you can increase your LT by doing tempo runs, you can reduce the accumulation of lactic acid and run faster without suffering muscle fatigue.

The increase in lactate threshold from regular tempo runs is particularly important for people preparing for half marathons and marathons. The pace you can sustain for long distances will be faster before the build-up of lactic acid sets in.

What Are the Benefits of Including Tempo Runs In Your Running Program?

There are many benefits to regularly running tempos. If performed consistently and correctly, they provide both physiological and mental benefits.

The efficient functioning of an athlete’s cardiovascular system is a key determinant of performance.

The ability to supply the muscles continuously with adequate levels of oxygen is sometimes referred to as aerobic capacity. By training at your tempo pace, it is possible to increase this aerobic capacity and delay the onset of lactic acid.

In a study carried out by a team of exercise physiologists led by Bertil Sjodin back in 1982, first introduced the term vOBLA – the speed at which there was an ‘onset of blood lactate accumulation’ (OBLA).2Sj�din, B., Jacobs, I., & Svedenhag, J. (1982). Changes in onset of blood lactate accumulation (OBLA) and muscle enzymes after training at OBLA. European Journal of Applied Physiology and Occupational Physiology49(1), 45–57. https://doi.org/10.1007/bf00428962

‌This is widely regarded as tempo pace.

After asking eight distance runners to do weekly 20-minute training runs at their OBLA pace, they found that their OBLA paces dropped by 4% (from 5:43 per mile to 5:29) after 14 weeks of training.

A more recent study in 2001 by Nicholson and Slevivert found that this pace vOBLA is an excellent predictor of performance in longer races, such as 10,000 meters and marathons.

Tempo runs are also helpful for developing the mental toughness and stamina needed for racing since you will have practiced running at a pace that is a little outside of your comfort zone.

Additionally, according to experienced UK athletics coach Mark Kirk, most people struggle to get their pace right:

Tempo running is the bread and butter for endurance runners, and it is crucial for aerobic development, but they must run at the correct pace! It is very much misunderstood, and I see many athletes who run their tempo sessions much too fast.”

Therefore, the pace at which you run your tempo is vital to get right. Remember, it’s not an all-out effort!

What Pace is Right for Your Tempo Run Workouts?

Finding the right tempo run pace will at first require a little experimenting, but a general rule of thumb is that it is the pace you could sustain for an hourit is usually considered to be between your 10k and half marathon pace, but closer to the latter.

If you only have race times from shorter distance races such as 5k, a general rule of thumb is to add 15-20 seconds per km/ 30 seconds per mile to your 5k race pace to determine the appropriate tempo pace.

It can be described as a “comfortably uncomfortable pace.” – or 5-6 out of 10 in RPE. You certainly wouldn’t be able to hold a conversation running at this pace, but you also don´t want to feel overly exhausted after it either.

However, there are more scientific methods for determining the right pace. For instance, if you normally use a heart rate monitor and know your maximum heart rate, you should aim to run the tempo session between 80-85% of that figure.

Moreover, one of the most widely used terms in sports science when referring to an athlete’s aerobic capacity is VO2 max.

VO2 max is defined as the maximum oxygen consumption rate as measured during incremental exercise. It indicates how efficiently an individual uses oxygen while exercising.

By undertaking a specific test to find your VO2 max, you’ll also be given details of where you reach your lactate threshold, providing you with the pace at which you should run your tempos. 

Additionally, some running coaches use devices to measure the blood lactate of their athletes.

The classic threshold level is 4mmol, so if athletes produce blood lactate above this level, it would indicate that they are not running their tempos at the right pace.

Whichever method you use, remember that the key is to run it at the desired effort level, and perhaps considering how you feel afterward is as good a clue as any.

As Mark Kirk states: “If an athlete finishes a tempo breathing heavily and putting hands on knees, then that indicates they have run too fast.”

How Do You Incorporate Tempo Run Sessions Into Your Training?

The first recommendation is to concentrate on your pace and not turn tempo runs into races.

This is common in a group training setting as you can easily get strung along at a faster pace with other runners, so sticking to your desired effort is essential.

The key is to run at the appropriate pace to recover and still complete the rest of your weekly training sessions without too much fatigue.

Although it is the pace that you could theoretically sustain for an hour, you should be doing much shorter tempo runs as part of your training to avoid burning out and exhausting yourself.

If you’re starting with tempos, you could start with one effort of 10 minutes and then build to 15 minutes after a few weeks. Then, aim for a duration between 20 and 25 mins.

For less experienced runners, a way of getting used to your threshold training tempo pace is to run intervals at that pace: 5 x 1km with a 1-minute recovery or 3 x 2k with a 90-second recovery are good examples of appropriate sessions.

How to Build Tempos into Your Yearly Plan

Tempo run sessions can have a place in an athlete´s schedule throughout the training year and in each of the periodization training traditional cycles: base, build, and peak.

The importance of tempos varies during the cycle. It is also usual to vary the pace and duration and maybe make them part of another session.

A tempo session once per week is essential for those wishing to run well over 5km, 10km, and half-marathon distances. It can be used to boost the development of aerobic endurance during the base phase.

The following are ways you can get the most out of your tempo sessions:

#1: Winter – 1 Per Week

Starting with a 20-minute tempo session and including some of 22 and 24 minutes and reaching 30 minutes over 12 weeks should be easy to fit into the schedule.

The tempo pace over this period will be well established, and you would expect the pace to be quick as you build endurance.

#2: Combined with Hills Session

The same as above but with some short hills for developing power and speed to be included after the tempo run. 4 x 15 seconds or 4 x 30 seconds on a steep hill is recommended.

#3: Before a Key Track Session

While in the pre-competition and competition phases, you´ll focus on high-quality interval workouts. However, one way to maintain aerobic development is to run a short tempo before or after a track session.

An example would be a 2-mile tempo, followed by a 3k pace workout of 12 x 400m, 60 seconds recovery. Or 1-mile tempo, followed by 5 x 600 at 3k pace.

#4: Long Tempos for Marathon Training

For those preparing for marathons, you could include a long tempo of between 40 and 70 minutes as part of your preparation. The pace would be at the low end of your tempo pace.

#5: Split Tempo

A popular session would be 10 mins at tempo pace, short hills, 8 mins at tempo pace, 6 long strides. This allows the athlete to incorporate both strength and speed into the combined session.

There you have it, some of the best speed work sessions to work into your training program to really boost your running and fitness level for your distance running.
