About the Pace Calculator

This pace calculator helps runners and cyclists determine their pace per kilometer or mile, speed, distance, or finish time. Enter any two values to calculate the third. It also provides race time predictions based on your current pace for common race distances: 5K, 10K, half marathon (21.1K), and full marathon (42.2K).

The Formula

Pace = Time / Distance · Speed = Distance / Time · Distance = Speed × Time

Frequently Asked Questions

What is a good running pace for beginners?

A comfortable running pace for beginners is typically between 6:00 and 8:00 min/km (9:40 to 12:50 min/mile). The key is to maintain a conversational pace — you should be able to speak in full sentences while running. Focus on building endurance before speed.

How do I improve my running pace?

To improve your pace, incorporate interval training, tempo runs, and strength training into your routine. Gradually increase weekly mileage by no more than 10% per week to avoid injury. Consistent training is more important than running every workout at maximum effort.
