A pace calculator computes your running pace, total time, or distance covered based on the two values you enter. Whether you are training for a 5K, marathon, or simply tracking a jog, it converts between min/mi, min/km, mph, and km/h so you can hit your target splits.
Pace Calculator formula
Pace = Time ÷ Distance. Time = Pace × Distance. Distance = Time ÷ Pace. To convert min/km to min/mi, multiply by 1.609; to convert min/mi to min/km, divide by 1.609. Speed in mph = 60 ÷ pace (min/mi).
How to use the Pace calculator
1Enter any two of distance, time, and pace.
2Choose your preferred units (miles or kilometers).
3Click Calculate to solve for the third value.
4Use the results to plan race splits or training runs.
Example calculation
A runner completes a 10K (6.21 miles) in 50 minutes. Pace = 50 ÷ 6.21 = 8.05 min/mi = 8:03 per mile, or 5:00 per kilometer. Equivalent speed = 60 ÷ 8.05 = 7.45 mph (12 km/h).
Frequently asked questions
What is a good running pace?
For recreational runners, a pace between 9:00 and 12:00 per mile (5:35–7:27 per km) is typical. Competitive amateur men average 7:00–8:30 min/mi and women 8:00–9:30 min/mi; elite marathoners run under 5:30 per mile.
How do I calculate my pace per mile?
Divide total time by total distance. For example, 40 minutes over 4 miles = 40 ÷ 4 = 10:00 per mile. This calculator handles the math and unit conversion automatically.
How do I convert min/km to min/mi?
Multiply min/km by 1.609 to get min/mi. A 5:00/km pace is roughly 8:03/mi. Conversely, divide min/mi by 1.609 to get min/km.
What pace do I need to finish a marathon in 4 hours?
A 4-hour marathon needs an average pace of 9:09 per mile (5:41 per km) across the 26.2-mile (42.2 km) distance.
