About Running Pace Calculator

The Running Pace Calculator converts your distance and finish time into pace (min/km, min/mi) and speed (km/h, mph). It supports metric & US units (km/mi) with race presets (5K, 10K, Half Marathon, Marathon) or a custom distance.

Knowing your running pace helps set realistic goals, plan negative splits, and project finish times for upcoming races. Pair it with VO₂ Max and Heart Rate Zones to structure training by effort.

FAQ

  • How do I calculate running pace?
    Enter distance and time — you’ll get pace in min/km and min/mi, plus speed in km/h and mph.
  • What is a good running pace?
    Varies by fitness and distance. Many recreational 5K runners fall around 4:30–7:00 min/km (7:15–11:15 min/mi).
  • How do I predict race finish time?
    The tool projects finish times from your current pace for 5K, 10K, half, and marathon; terrain and weather still matter.
  • Can I switch between kilometers and miles?
    Yes — pick km or mi in the unit selector; outputs show both pace formats.
  • How do heart rate and VO₂ Max affect pace?
    Better aerobic fitness supports faster sustainable paces. See VO₂ Max and HR Zones.
