What Is a Tempo Run? Effort, Pace and Workout Examples

In Jack Daniels’ framework, threshold effort is roughly the intensity you could race for an hour under good conditions. It should be controlled rather than all-out. It is not the same fixed distance pace for everyone.

Daniels describes continuous threshold running and repetitions with short recoveries. A continuous 20-minute threshold segment is one example in that system, not a requirement for new runners. Total harder running should fit the wider plan.

For a runner already accustomed to harder sessions, an example is an easy warmup, a controlled tempo segment and easy running afterward. Shorten the harder portion or use the repetitions in your plan when a continuous effort is too demanding. These are workout examples, not claims that a cooldown prevents soreness.

Enter a recent result into the Anystride calculator for an estimated threshold pace. Its model is not a direct measurement of your lactate threshold. Adjust for heat, hills, fatigue and current effort instead of forcing a number or subtracting a fixed number of seconds from easy pace.

A tempo session counts as harder work. Leave room to recover and account for the long run and any other demanding sessions. Beginners can build a repeatable easy-running routine first; a weekly tempo run is not necessary for everyone.

A session labelled marathon-pace tempo may be slower and longer than threshold work. Follow the plan’s intended intensity rather than substituting threshold pace for every workout called tempo.
