How it works
Calculate your running pace per km or mile, get split times, and predict finish times for 5K, 10K, half marathon, and marathon distances. Enter your distance and time to find your pace, or enter a target pace to find your finish time. Essential for race planning and training.
How to Use This Calculator
- Enter your distance in km or miles.
- Enter your time (hours, minutes, seconds).
- Choose your preferred pace unit (min/km or min/mile).
- Review your average pace and split times.
Example
Inputs: 5 km run in 25 minutes
Result: 5:00 min/km (8:03 min/mile)
What it means: A 5:00 min/km pace is a solid recreational runner pace β equivalent to about a 25-minute 5K.
Tips
- Track pace trends over weeks rather than individual runs.
- Include warm-up and cool-down time in your total session.
- Your race pace should be slightly faster than your training pace.
- Easy runs should feel conversational β if you can't talk, slow down.
Frequently Asked Questions
- How do I calculate my running pace?
- Divide your total time by the distance covered. For example, if you run 5 km in 25 minutes, your pace is 5:00 per kilometer. This calculator can also work in reverse, estimating your finish time from a target pace and distance, or the distance you would cover at a given pace and time.
- What is a good running pace for beginners?
- Most beginner runners start at a pace of 6:30 to 8:00 per kilometer (10:30 to 12:50 per mile). The key for beginners is to run at a conversational pace where you can speak in full sentences without gasping. Speed improves naturally with consistent training over weeks and months.
- How do I use pace to plan a race?
- Start by determining your goal finish time and divide by the race distance to get your required average pace. For a 5K in under 25 minutes, you need a pace of under 5:00/km. It is wise to practice running at your goal pace during training so your body is comfortable sustaining it on race day.
