Free Pace Calculator

Find your running pace and predict times for common race distances.

Race time predictions here assume a flat, even-effort pace — real race performance varies with course terrain, taper, and how well-trained you are for the specific distance (marathon pace is typically slower than your 5K pace per mile due to endurance demands).

Frequently Asked Questions

Is my marathon time really at the same pace as my 5K?
Not usually — most runners slow down over longer distances. Treat these as a starting-point estimate, not a guarantee.
