Understand the calculation

Pace is time divided by distance. Speed is distance divided by time in hours. Each split uses exact values; only the display is rounded.

Your questions, answered

Do I need an account to calculate?

No. Results and methods are freely available.

What does saving keep?

Your inputs, result and method version, in your private resources. Your plan and personal records are not changed.

Why can an estimate differ from my race?

The calculation does not know every condition or your preparation. A theoretical equivalent helps you explore a goal and compare it with your training.
