Frequently asked questions
Is it free?
Yes — it is free with no sign-up, no watermark and no account-based quota. Your browser, device memory and the bench's stated file limits still determine how much it can process at once.
Is my data private?
Nothing is uploaded. This tool runs entirely in your browser, so your data is processed on your own device and never sent to a server.
Which two running values do I need?
Enter any two of distance, elapsed time and pace. The calculator derives the missing value and supports kilometres or miles.
