Pace Calculator
Calculate the pace you need to hit a goal finish time, or find your finish time from a known pace — for 5K, 10K, half marathon, marathon, or any custom distance.
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.
