Calculate your running pace and speed with our Running Pace Calculator. Enter your distance and finish time (hours, minutes, seconds) to get your pace per kilometer and per mile, plus your speed in km/h and mph.
Pace is the number runners train by: time divided by distance. A 5K in 25 minutes is 5:00 min/km; a sub-2-hour half marathon demands about 5:41 min/km. The calculator converts between min/km and min/mile automatically — essential when following training plans from different countries.
Use it to plan race strategy (what pace do I need for a goal time?), analyze training runs, or compare treadmill speed settings (km/h or mph) with your outdoor pace. Typical recreational pace sits around 5:30-6:30 min/km — but the only pace that matters is the one that matches your own goal.
