Pace Calculator

Calculate your running pace, finish time, or distance for any race. Supports min/km and min/mi formats.

Loading...
1. Choose which variable to solve for - pace, time, or distance. 2. Enter the two known values (for example, distance and finish time). 3. View your calculated pace in both min/km and min/mi formats. 4. Check estimated finish times for standard race distances (5K, 10K, half marathon, marathon). 5. Use the speed equivalents in km/h and mph for cross-training reference.

About This Tool

Whether you are training for a 5K or a marathon, understanding your pace is essential for race planning and performance tracking. Our Pace Calculator lets you solve for any one of the three key running variables - pace, time, or distance - when you know the other two.

Enter any combination of values and the calculator instantly shows your results in both metric (min/km, km/h) and imperial (min/mi, mph) formats. It also provides estimated finish times for popular race distances including 5K, 10K, half marathon, and full marathon based on your current pace.

Use the calculator to set realistic race goals, plan negative splits (running the second half faster), or compare your training paces across different workout types. Knowing your easy pace, tempo pace, and race pace helps you structure training plans that build fitness without overtraining.

Formula / How It Works

Pace = Time / Distance. Time = Pace x Distance. Distance = Time / Pace. Speed (km/h) = 60 / pace (min/km).

Frequently Asked Questions

A comfortable beginner pace is typically 7:00-9:00 min/km (11:00-14:30 min/mi). The best pace for beginners is one where you can hold a conversation. Do not worry about speed - consistency and building a running habit matter more initially.
Divide your total time by the distance covered. For example, if you ran 5 km in 30 minutes, your pace is 30 / 5 = 6:00 min/km. Most running watches and apps calculate this automatically.
Pace is the time it takes to cover a unit of distance (e.g., 5:30 min/km). Speed is the distance covered per unit of time (e.g., 10.9 km/h). They are inversely related - a faster pace means higher speed. Runners typically use pace, while cyclists use speed.
Incorporate interval training (short fast efforts with rest), tempo runs (sustained comfortably hard pace), and long slow runs into your weekly routine. Gradual increases of 5-10% in weekly mileage and consistent training over months will naturally improve your pace.
To finish a marathon in under 4 hours, you need to maintain an average pace of 5:41 min/km (9:09 min/mi) or faster over the full 42.195 km (26.2 mi) distance.
