Speed (km/h) = 60 / Pace (min/km)

Example: 6:00/km pace = 60/6 = 10 km/h

Training Pace Zones

  • Easy run: 60–70% max HR, should hold a conversation
  • Tempo: Comfortably hard, can speak in short phrases
  • Threshold: 85–90% max HR, speech difficult
  • Intervals: 90–100% max HR, near-maximum effort
