About this tool
This page opens the running pace calculator with a 5K in 25:00 already filled in: the required pace is 5:00 per kilometer, which equals 8:03 per mile or a steady 12.0 km/h (7.5 mph).
A 25-minute 5K is a popular milestone for regular runners — it usually takes a few months of consistent training after the beginner stage. The split table shows what your watch should read at every kilometer: 5:00, 10:00, 15:00, 20:00 and 25:00 at the finish.
Change the time or distance to test other goals, switch to time mode to project a finish from a pace you can hold, or use the predictor to estimate your 10K, half and marathon from this 5K result.
Example. Five kilometers in 25:00 is a pace of 5:00 per kilometer and 8:03 per mile.
Limit. Race-time predictions use the Riegel exponent 1.06 on the built-in distances 5K, 10K, half marathon, and marathon.
