The same average pace can mean very different things at different distances. Use the calculator for the math, then choose a target that matches your recent training.
25:00 5K
8:03/mi / 5:00/km
Useful for a first structured 5K time goal.
50:00 10K
8:03/mi / 5:00/km
Same pace as a 25-minute 5K, but harder because it lasts twice as long.
2:00 half marathon
9:09/mi / 5:41/km
A common target where pacing discipline matters more than early speed.
4:00 marathon
9:09/mi / 5:41/km
The same average pace as a 2-hour half, held for the full marathon.
How this calculator works
This calculator uses the standard distance-speed-time relationship to convert between pace, finish time, and distance. Enter any two values to solve for the third. Results are displayed in both miles and kilometers for convenience. Standard race distance shortcuts (5K, 10K, Half Marathon, Marathon) are included for quick calculations.
