Calculate your running pace, finish time, or distance. Convert between pace (min/mile or min/km) and speed (mph or km/h). Perfect for race planning and training.

Pace Formula: Pace = Total Time / Distance
For example, running 5K (3.1 miles) in 25 minutes gives a pace of 25 / 3.1 = 8:04 per mile.
Pace to Speed
Speed (mph) = 60 / Pace (min/mile)
Mile to KM
Pace/km = Pace/mile / 1.609

Based on your results
At 8:03/mile (5:00/km), you're at an intermediate level. Incorporate tempo runs to improve.
For faster race times, do 800m repeats at 7:15 pace with equal rest.
For consistent improvement, keep 80% of runs easy (9:39/mi) and 20% hard.
Running pace is the amount of time it takes to cover a specific distance, typically expressed as minutes per mile or minutes per kilometer. A faster pace means a shorter time per distance unit. For example, a 8:00/mile pace means you run each mile in 8 minutes.
Divide your total running time by the distance covered. If you ran 3 miles in 24 minutes, your pace is 24/3 = 8 minutes per mile. Our calculator handles all the conversions between miles, kilometers, and different time formats automatically.
A good beginner pace is typically 10-12 minutes per mile (6:15-7:30 per km). The key is maintaining a conversational pace where you can speak in full sentences. As fitness improves, most runners can achieve 8-10 minute miles with consistent training.
Race pace predictions estimate finish times for different distances based on your current fitness. Generally, pace slows as distance increases. If you run a 25-minute 5K (8:03/mi), you might expect a 52-minute 10K (8:23/mi) and a 1:55 half marathon (8:47/mi).
Speed (mph or km/h) is the inverse of pace. A 10:00/mile pace equals 6 mph. A 6:00/mile pace equals 10 mph. Speed is useful for treadmill settings and comparing to cycling or other activities. Pace is more intuitive for planning runs.
