Calculate your running pace from distance and time
0 h · 25 min · 30 sec
Pace is the time it takes to cover a specific distance, usually expressed in minutes per kilometer (min/km) or minutes per mile (min/mi). Unlike speed in km/h, pace shows how long each kilometer “costs” — making it easier to control effort in workouts and races. On a GPS watch, average and current pace help you avoid starting too fast and fading at the end.
Controlling pace reduces overload, improves training consistency and supports gradual progression. Runners who monitor pace tend to have lower injury risk and a better chance of hitting 5K, 10K or half-marathon goals. Use target paces for easy long runs, threshold work and intervals. The calculator also converts min/km ↔ km/h so training aligns with race goals and plans.
Use the tabs to calculate pace (distance + time), distance (pace + time), time (distance + pace) or convert units. Plan race goals: a 30-minute 5K needs about 6:00 min/km. Beginners should stay at a conversational pace. Experienced runners can cross-check results with the race time predictor and heart-rate zones.
