Pace Calculator — Running Pace, Speed, Time
Calculate your running or walking pace, finish time, or distance. Supports miles and kilometers with split time table. See also our Calories Burned Calculator and Speed Calculator.
How to Calculate Running Pace
- Select what you want to calculate: pace, finish time, or distance.
- Enter the known values (distance and time, or pace).
- Choose your distance unit (km or miles).
- Click Calculate to see your result with split times.
- Use split times to plan your race strategy.
Formula
Pace = Time / Distance (minutes per km or mile)
Speed = Distance / Time (km/h or mph)
Time = Pace x Distance
Distance = Time / Pace
Example
Distance: 5 km, Time: 25:00
Pace = 25 min / 5 km = 5:00 per km
Speed = 5 km / (25/60) h = 12 km/h

Frequently Asked Questions
What is a good running pace for beginners?
A comfortable beginner pace is typically 6:30-8:00 per km (10:30-13:00 per mile). Focus on consistency rather than speed when starting out.
How do I convert pace from min/km to min/mile?
Multiply your min/km pace by 1.60934. For example, 5:00/km = approximately 8:03/mile.
What is negative splitting?
Running the second half of a race faster than the first half. This is considered an optimal race strategy for most distances.
How can I improve my pace?
Include interval training, tempo runs, and long slow runs in your training. Consistency and gradual progression are key to pace improvement.
What pace do I need for a sub-4-hour marathon?
You need to maintain approximately 5:41 per km (9:09 per mile) to finish a marathon in under 4 hours.
