Tempo pace is a comfortably hard effort you can sustain for 20-60 minutes. It sits around your lactate threshold — the point where lactate begins accumulating faster than it can be cleared. It feels hard but controlled, and you should be able to speak in short phrases.

How do I calculate tempo pace from a 5K time?

Tempo pace is typically 25-30 seconds per km slower than your 5K pace. For example, if you run 5K in 25 minutes (5:00/km pace), your tempo pace is approximately 5:25-5:30/km. This calculator automates this conversion using training pace formulas.

What is the difference between tempo pace and marathon pace?

Tempo pace (lactate threshold) is faster than marathon pace. For most runners, marathon pace is 15-30 seconds per km slower than threshold pace. Marathon pace training develops efficiency at race pace, while tempo develops lactate clearance ability.

What are cruise intervals?

Cruise intervals are tempo-paced repetitions with short rest periods (60-90 seconds). Popularised by Jack Daniels, they allow you to accumulate more time at threshold pace than a continuous tempo run. A typical session is 5 x 1000m with 60s jog recovery.

Should I run tempo by pace or heart rate?

Both methods work. Pace is more precise but does not account for fatigue, heat or hills. Heart rate adapts to conditions but lags behind effort changes. Ideally, use pace on flat routes in cool weather, and heart rate on hilly or hot days.

How We Calculate This

Pace Estimation

Tempo pace is calculated from your race result using Daniels VDOT methodology. Different tempo types (lactate threshold, marathon pace, cruise intervals) yield different training paces.

VDOT

VDOT is a measure of running fitness derived from race performance. It normalises performance across distances and provides corresponding training pace zones.
