Running Pace Calculator | Pace, Speed and Finish Time
Calculate running pace per kilometer, speed, or estimated finish time from distance and duration for training runs and race planning.
Calculate Running Pace from Distance and Time
Enter race distance and finish time to calculate pace per kilometer, average speed, and timing targets for training plans, tempo runs, and race goals.
Use Realistic Race and Training Inputs
Pace estimates do not account for hills, heat, wind, trail surface, fatigue, or aid stops. Treat the number as a planning target, not a guarantee.
When Runners Use Pace Math
Use it for 5K, 10K, half marathon, marathon, treadmill sessions, interval planning, long-run pacing, and checking whether a goal time matches your current training.
About This Tool
Running Pace Calculator converts between pace, speed, and distance to help runners plan training and race strategy. It calculates finish time from pace and distance, pace from a target finish time, or speed from pace.
When to Use It
Use this when planning a race strategy and you want to know what pace to maintain for a target finish time, when converting between minutes per kilometre and minutes per mile, or when setting a treadmill speed.
How to Use

Frequently Asked Questions
What is a good 5K pace for a beginner?
Most beginners complete a 5K in 35 to 45 minutes, which is a pace of 7 to 9 minutes per kilometre. Anything under 30 minutes is considered a solid recreational runner time.
How do I convert min/km to km/h?
Divide 60 by your pace in minutes per kilometre. A pace of 6 min/km equals 10 km/h. The calculator handles this conversion automatically.
What pace do I need for a sub-2-hour half marathon?
A sub-2-hour half marathon requires a pace of 5 minutes 41 seconds per kilometre or 9 minutes 9 seconds per mile.
