Pace & speed
Pace = time ÷ distance · Speed = distance ÷ time
Pace (minutes per km or mile) is how runners plan races; speed (km/h or mph) is what treadmills show. Example: 25:00 over 5 km = 5:00 /km = 12 km/h. Even, sustainable pacing almost always beats starting too fast.
Find your pace
Pace is time divided by distance. Enter a distance (in km or miles) and finish time — or tap a race preset — and see your pace per mile and per km side by side, plus speed. Runners use pace to plan even splits.
