Quick answer: Pace = Time ÷ Distance. Use our free Running Pace Calculator to convert between pace, time, and distance instantly.
Three Ways to Use This
Find your pace: enter time and distance to get minutes per mile/km. Predict finish time: enter your pace and race distance. Find distance: enter your pace and available time to see how far you could run.
Why Pace Matters for Training
Training at a specific target pace (rather than just "running") helps build the right energy systems for your race goal, whether that's a 5K sprint pace or a marathon endurance pace.
Frequently Asked Questions
How do I predict my marathon finish time from a 5K pace?
Enter your known pace and the marathon distance (26.2 miles) to estimate a finish time — though actual marathon pace is usually slower than 5K pace due to endurance demands.
Does this work in both miles and kilometers?
Yes, the calculator supports both units.
Is pace the same as speed?
They're inverses — pace is time per distance (minutes/mile), speed is distance per time (miles/hour).

Pace is time per unit of distance. If you run 5 kilometres in 30 minutes, divide 30 by 5 to get 6 minutes per kilometre. For miles, divide total minutes by miles completed. Keep the distance unit attached to the result: 6:00 min/km and 6:00 min/mi describe very different speeds.
For a finish-time estimate, multiply your pace by the target distance. At 6:00 min/km, a 10 km run would take about 60 minutes if you maintained the same pace. This is a simple projection; hills, weather, fatigue, stops, and race conditions can change the actual time.
Use lap splits to understand pacing
Compare each kilometre or mile split rather than relying only on the overall average. A much slower final split can signal that the opening pace was difficult to sustain, while a steady split pattern helps you plan future runs. GPS watches can mismeasure distance around buildings, trees, or tight turns, so a marked course may produce a more reliable comparison.
Increase training gradually and include recovery. A pace calculator can help with arithmetic, but it cannot assess injury, fitness, or medical readiness. Stop if you feel unwell and seek appropriate medical advice for concerning symptoms.
Convert pace without mixing units
To change minutes per kilometre into minutes per mile, multiply by about 1.609. A pace of 6:00 min/km is approximately 9:39 min/mi. Convert the full time value, not just the minutes: six minutes is 360 seconds, and 360 × 1.609 is about 579 seconds. That is 9 minutes 39 seconds. This avoids the common mistake of multiplying “6” and leaving the seconds unchanged. Keep the original unit visible in notes and training plans.
