Speed Work vs Tempo Runs: When & How to Use Them

in
Running is more than just putting one foot in front of the other. To become a stronger, faster, and more efficient runner, it’s important to incorporate different types of workouts into your training plan. Two of the most effective workouts are speed work and tempo runs. But what’s the difference between them, and when should you use each? Let’s break it down.

Speed work refers to short, intense bursts of running, usually at a pace much faster than your typical run. These workouts include intervals, sprints, and repetitions, often with rest periods in between. The goal is to improve your maximum speed, running economy, and anaerobic capacity.
Examples of Speed Work:
  • 400m repeats at mile pace with full recovery
  • 8 x 200m sprints with walking rest
  • Hill sprints
Benefits:
  • Increases top-end speed
  • Improves running form and efficiency
  • Builds strength and power

 

What is a Tempo Run?A woman jogs along a seaside promenade at sunrise, the sun low behind her. Dressed in athletic clothing, she appears focused on her running training as she runs near the water. Austin Marathon Half Marathon & 5K

A tempo run, also known as a threshold run, is a sustained effort at a “comfortably hard” pace—usually about 80-90% of your maximum effort. This pace is often described as the fastest you can maintain for about an hour. Tempo runs are designed to improve your lactate threshold, which is the point at which fatigue rapidly increases.

 

Examples of Tempo Runs:
  • 20-minute run at threshold pace
  • 4 miles at tempo pace within a longer run
  • 2 x 15 minutes at tempo pace with short recovery
Benefits:
  • Increases endurance
  • Raises lactate threshold
  • Teaches your body to run faster for longer

 

When to Use Speed WorkTwo people in dark athletic wear are jogging side by side outdoors on a paved path, trees and buildings blurred in the background, suggesting fast motion—perfect for a tempo runs session during their running training. Austin Marathon Half Marathon & 5K

  • Early in a training cycle: Build speed and power before focusing on longer efforts.
  • Race-specific prep: For shorter races (5K/10K), speed work is crucial.
  • Breaking through plateaus: If you feel stuck at a certain pace, speed work can help you break through.

 

When to Use Tempo Runs

  • Mid to late training cycle: As you build toward a goal race, tempo runs help you sustain faster paces.
  • Half marathon/marathon prep: Essential for longer distances to improve stamina.
  • Improving race pace: Tempo runs help you get comfortable running at your goal pace.

A balanced training plan will include both speed work and tempo runs. For example, you might do speed intervals on Tuesdays and a tempo run on Thursdays, with easy runs and long runs on other days. Always listen to your body and allow for adequate recovery.

 

Sample Week:
  • Monday: Easy run
  • Tuesday: Speed work (e.g., 8 x 400m)
  • Wednesday: Rest or easy run
  • Thursday: Tempo run (e.g., 20 minutes at tempo pace)
  • Friday: Easy run
  • Saturday: Long run
  • Sunday: Rest

 

Final Thoughts

Both speed work and tempo runs are essential tools for runners aiming to improve performance. By understanding when and how to use each, you’ll be able to train smarter, avoid burnout, and reach your running goals faster. Happy running!
