How to use the pace calculator
This tool solves the same equation three ways: pace = time ÷ distance. Fill in the two values you know on any tab, and the third updates instantly as you type. Use the preset chips for common race distances, or enter a custom distance in miles or kilometers.
Why your pace matters more than your speed

Knowing your current pace at a few distances is the foundation for the Race Time Predictor and Split Calculator below.
