Running Pace Calculator
Whether you need to know your pace per kilometer, convert to miles, or figure out what pace you need to hit a specific finish time — this calculator handles it all. Enter any two values and get the third instantly. Essential for race planning, training targets, and understanding your running speed.
How it works
The pace calculator uses simple but precise conversions between time, distance, and speed. Enter your finish time and distance to get pace per kilometer and per mile. Or enter your target pace and distance to see your projected finish time. All calculations account for the exact distance of standard race courses.
Training advice
Understanding pace is fundamental to smart running. For easy runs, aim for a pace 60-90 seconds slower than your 5K race pace. Tempo runs should feel 'comfortably hard' at roughly your half marathon pace. Learn to run by feel as well as by watch — conditions, terrain, and fatigue all affect what pace is appropriate on any given day.
Frequently asked questions
What is a good running pace?
It depends entirely on your fitness level and goals. For beginners, 6:00-7:00 min/km is typical. Intermediate runners often settle around 5:00-5:30 min/km for easy runs. Competitive runners train at 4:00-4:30 min/km for easy efforts.
How do I convert pace from km to miles?
Multiply your pace per kilometer by 1.60934 to get pace per mile. For example, 5:00/km equals approximately 8:03/mile.
What pace do I need for a sub-2 hour half marathon?
You need to average approximately 5:41 per kilometer or 9:09 per mile to finish a half marathon in under 2 hours.
Should I run at the same pace every day?
No. Effective training uses different paces for different purposes. Easy runs, tempo runs, intervals, and long runs should all be at distinct paces. Running every day at the same moderate effort is one of the most common training mistakes.
