Marathon Pace Calculator

This calculator helps you determine the pace you need to maintain throughout your race to achieve your target finish time. Simply select your race distance, enter your goal time or target pace, and the calculator will show you the exact pace per kilometer and per mile.

The split times table shows you projected checkpoint times throughout your race. You can choose between 5km and 1km intervals to match your preference. When using miles, splits are shown at every mile automatically.

You can toggle between kilometers and miles using the unit switch button. Your inputs are automatically saved for quick access the next time you visit.
