Frequently Asked Questions
What are training paces?
Training paces are target speeds for different types of runs: e.g. easy, tempo, threshold, interval. They are often derived from a recent race time or goal race pace (e.g. marathon or 5K) using tables or formulas like Jack Daniels' VDOT.
How do I calculate training pace?
Enter a recent race distance and time (or a target race and time). This calculator estimates equivalent performance at other distances and suggests easy, tempo and marathon paces as a percentage of that effort. Formulas are simplified; full systems like VDOT use more data.
Is the training pace calculator free?
Yes. Free to use. For guidance; adjust to feel and conditions.
What is easy pace?
Easy pace is a comfortable, conversational effort—often about 60–75% of max or roughly 1–2 min/mile slower than marathon pace. Used for recovery and base runs.
