Use the zones: Apply the suggested paces to workouts and long runs.

Frequently asked questions

Is 10K pace the same as threshold pace?

Not exactly. 10K pace is typically faster than threshold pace. Threshold pace is the effort you can hold for about an hour.

Can I use a 10K time to train for a marathon?

Yes. A strong 10K provides a fitness anchor for training zones, then you build marathon-specific endurance with long runs and steady efforts.
