Frequently Asked Questions

Pace Zones

Pace zones are specific pace ranges for different training intensities. Each zone targets different physiological adaptations, from easy recovery runs to high-intensity intervals.

Threshold pace is approximately the pace you could sustain for 60 minutes all-out, or about 10K race pace for most runners. You can also estimate it from a recent race time.

Training in the right zones ensures you get the intended benefit from each workout. Running too fast on easy days or too slow on hard days reduces training effectiveness.
