A tempo run is a sustained effort at threshold pace, typically lasting 20-40 minutes. It feels comfortably hard — you can speak in short phrases but not hold a full conversation.

How far should a tempo run be?

Tempo runs typically range from 5-10 km at threshold pace. Begin with 20 minutes and gradually extend to 40 minutes as fitness improves.

What is the difference between tempo and threshold?

They are often used interchangeably. Strictly, threshold pace is the exact pace at lactate threshold. Tempo pace is a slightly broader range around threshold, making it more practical for training.

How We Calculate This

Tempo Pace

Tempo Pace = Race Pace × 1.05-1.10

Tempo pace is slightly slower than your 10K-15K race pace, sustainable for 40-60 minutes.
