You can find it at any time on the Running Pace Calculator page, where the calculator sits above a full explanation of the method it uses.
Tips for an accurate result
Treat any single result as one data point — trends over weeks matter far more than one reading.
Use the same units consistently (all metric or all imperial) — mixing unit systems mid-entry is a frequent source of errors.
If a result seems unusual, re-enter your inputs carefully before assuming something is medically wrong — a typo is far more common than an anomaly.
Use consistent measurement conditions each time (same scale, same time of day) so results are comparable over time.
