Overview

Calculate your average running pace (min/km) and speed (km/h) from distance and time. Also estimates finish times for popular race distances including 5K, 10K, half marathon, and full marathon.

Formula

Pace (min/km) = Total Time (min) ÷ Distance (km)
Speed (km/h) = Distance (km) ÷ Total Time (hours)
Finish Time = Pace (min/km) × Race Distance (km)

Race Distances:
• 5K = 5.0 km
• 10K = 10.0 km
• Half Marathon = 21.0975 km
• Marathon = 42.195 km

How to Use

  1. 1Enter the distance you ran (e.g., 5 km).
  2. 2Enter your total time in HH:MM:SS format (e.g., 0:25:00).
  3. 3Your average pace (min/km) and speed (km/h) are calculated automatically.
  4. 4Estimated finish times for popular race distances are also displayed.

Tips

  • Set your race pace 10–20 seconds/km slower than your training pace for safety.
  • A negative split strategy (running the second half faster) often yields the best results.
  • Altitude, temperature, and humidity all affect your pace — factor in conditions.
  • During long runs, maintain a comfortable conversational pace (Easy Pace).
  • Compare with GPS watch data to develop an intuitive sense of pace.

FAQ

Q. What is a good running pace?

Pace varies by age, gender, and training level. General benchmarks: beginner runners target 6:30–7:30 min/km, intermediate runners 5:00–6:00 min/km, and advanced runners 4:00–5:00 min/km. The most important thing is to set a pace appropriate for your current fitness.

Q. How can I improve my pace?

Interval training (alternating fast and slow), tempo runs (slightly faster than race pace for a set distance), and increasing weekly mileage are the most effective methods. Include 1–2 speed sessions per week and keep the rest at easy pace.

Q. Is treadmill pace different from outdoor pace?

Yes. Treadmills lack wind resistance and the belt assists forward motion, making the same pace feel easier than outdoors. Setting a 1–2% incline on the treadmill is recommended to approximate outdoor effort.
