How to use the Pace Calculator
Select a race distance (or enter a custom distance) and your finish time. The calculator instantly shows your pace in both min/km and min/mile, plus your speed in km/h and mph. It also predicts equivalent race times at other standard distances using the Riegel formula — the industry standard for race time prediction.
What is running pace?
Running pace is the time it takes to cover one unit of distance (one kilometre or one mile). For example, a pace of 5:00/km means you run each kilometre in 5 minutes. Pace is the most common way runners measure and communicate their speed.
