Running Pace vs Speed: What Watch Displays Actually Mean
Pace and speed describe the same run in opposite directions. Learn the exact relationship, the conversion formula, and when each unit is useful.
Read guide →These guides explain the numbers behind the calculators: how pace and speed relate, how the kilometer and mile conventions convert, how to read and carry a split table, and what the gap between a plan and an actual race does and does not tell you. RunPaceKit is a calculator-first site, so every guide points back to the tool that does the arithmetic.
