Interval Pace Calculator

Whether you’re training for a 5K, marathon, or simply trying to improve your fitness, understanding your running pace is essential. Our Interval Pace Calculator is a free, user-friendly tool designed to help runners, cyclists, and fitness enthusiasts determine their pace per mile or kilometer, along with their average speed.

This tool is perfect for athletes tracking performance, coaches programming intervals, or beginners learning how long a run will take. With just a few clicks, you can calculate how fast you went or need to go.

🔧 What is the Interval Pace Calculator?

The Interval Pace Calculator converts a known distance and time into three key metrics:

  • Pace per kilometer (min/km)
  • Pace per mile (min/mi)
  • Speed in both kilometers per hour (km/h) and miles per hour (mph)

It’s ideal for runners, walkers, cyclists, and coaches planning interval workouts or tracking race performances.

🏃 Practical Example: Track Your 10K Run

Scenario: You ran 10 kilometers in 52 minutes and 30 seconds.
Let’s calculate:

  • Distance: 10
  • Unit: Kilometers
  • Time: 0 hours, 52 minutes, 30 seconds

Result:

  • Pace per km: 5:15 min/km
  • Pace per mile: 8:27 min/mi
  • Speed: 11.43 km/h or 7.10 mph

Now you can set training goals or adjust future sessions based on these results!

💡 Why Track Your Running Pace?

  • Monitor progress over time
  • Set realistic race goals
  • Optimize training intensity (easy, moderate, hard runs)
  • Plan interval workouts precisely
  • Compare performance across different distances

For coaches, it ensures athletes are performing at the right effort zones.
