Tempo Runs: The Workout That Made Me Faster

One speed workout a week was part of my 24-week plan. Here is how tempo runs work, and why I never skip them.

By Alex · 6 min read

My 24-week training plan had one simple structure:

• 1 long run per week
• 1 speed workout per week
• Easy runs 2 minutes slower than race pace

That speed workout was usually a tempo run. Here is why they work and how to do them properly.

What Is a Tempo Run?

A tempo run is a steady effort at a "comfortably hard" pace — faster than easy running, slower than racing. The aim is to run at or near your lactate threshold: the pace where your body clears lactate as fast as it produces it.

How it feels: you can say short phrases, but not full sentences. It is demanding, but you can keep it going.

Why Tempo Runs Work

At threshold pace you train your body to:

1. Clear lactate better - so the moment when you fall apart comes later
2. Run more efficiently - use less energy at faster paces
3. Build mental strength - practice staying calm while it hurts
4. Get race-ready - half marathon pace is close to threshold pace

Finding Your Tempo Pace

There are several ways to find it:

Method 1: Race Prediction

Use our Pace Calculator with a recent race time. Your threshold pace is usually:

• About 25-30 seconds per km slower than 10K pace
• About 15-20 seconds per km faster than half marathon pace

Method 2: Heart Rate

85-90% of your maximum heart rate.

Method 3: How It Feels

An effort of 6-7 out of 10. "Comfortably hard." You want to slow down, but you do not have to.

Tempo Run Formats

Classic Tempo (20-40 minutes)

The standard version:

• 10-15 min easy warm-up
• 20-40 min at tempo pace
• 10 min easy cool-down

Best for: general threshold work and half marathon training

Cruise Intervals

The tempo is broken into pieces with short recoveries:

• 3-4 x 10 minutes at tempo with a 2 min jog
• 5 x 6 minutes at tempo with a 90 sec jog

Best for: your first weeks of tempo training, and longer threshold sessions

Progression Tempo

Start slower, finish faster:

• First third at marathon pace
• Second third at tempo pace
• Last third at 10K effort

Best for: learning to finish races strongly

Common Tempo Mistakes

1. Running Too Fast

The most common error. If you are racing your tempo run, you have missed the point. It should feel controlled.

2. Running Too Long

More is not always better. 40 minutes of good tempo running beats 60 minutes of messy threshold running.

3. Skipping the Warm-Up

You need 10-15 minutes of easy running before you start tempo pace. Cold muscles do not respond well.

Sample Week with Tempo

This is close to what I did for 24 weeks. Simple, manageable, effective.

The Mental Game

Tempo runs teach you to be comfortable while you are uncomfortable. That carries straight over into racing:

• You learn what "hard but sustainable" feels like
• You practice staying calm when it gets tough
• You build confidence in your own fitness

By race day I knew exactly what tempo effort felt like. I trusted my legs because I had done the work.

Key Takeaways

1. Tempo = threshold pace = comfortably hard
2. Use the Pace Calculator to find your tempo pace
3. Start with 20 minutes and build up slowly
4. Do not race your tempo runs — control is everything
5. One tempo run a week is plenty for most runners

Regular tempo work will make you a faster and more confident racer. Trust the process.
