About this calculator

This pace calculator works in two directions. In Pace from time mode, enter a race distance and your goal finish time to find the per-mile and per-kilometer pace you need to maintain. In Time from pace mode, enter a distance and your known pace to find your projected finish time. Both modes also show a projection table with finish times at every standard race distance — 5K, 10K, half marathon, and marathon — at that same pace.
