How to Use This Calculator

  1. Choose what you want to calculate: pace from time/distance, or time from pace/distance
  2. Select your distance unit (kilometers or miles)
  3. Enter your distance (e.g., 5 for a 5K, 26.2 for a marathon)
  4. If calculating pace: enter your time in hours, minutes, and seconds
  5. If calculating time: enter your target pace in minutes and seconds per km/mile
  6. Click 'Calculate' to see results
  7. Review your pace (min per distance) and average speed
  8. Use this information to plan training runs or race strategies

Formula

Pace (min/distance) = Total Time (minutes) / Distance; Speed = Distance / Time; Time = Pace × Distance; 1 mile = 1.60934 km

Frequently Asked Questions

What is a good running pace?▼
A good pace depends on fitness level and distance. For casual joggers: 10-12 min/mile (6-7.5 min/km). For intermediate runners: 8-10 min/mile (5-6 min/km). For advanced runners: 6-8 min/mile (3.7-5 min/km). Elite marathoners run at ~4:40-5:30 min/mile pace.
How do I improve my pace?▼
Improve pace through: interval training (alternating fast and slow periods), tempo runs (sustained faster pace), hill training, strength training, consistent mileage buildup, proper rest and recovery, and good running form. Aim to improve gradually by 10-15 seconds per mile every few weeks.
Should my pace be the same for all distances?▼
No, pace varies by distance. You'll run faster per mile/km for shorter distances (5K) versus longer ones (marathon). A typical 5K pace might be 30-60 seconds per mile faster than your 10K pace, and 60-90 seconds faster than your half marathon pace.
What's the difference between pace and speed?▼
Pace is time per unit distance (e.g., 8 min/mile or 5 min/km) - commonly used in running. Speed is distance per unit time (e.g., 7.5 mph or 12 km/h) - commonly used for biking and other activities. They're inverse measures of the same thing.
