About Norwegian Singles

The Norwegian Singles method is a training approach that emphasizes sub-threshold training to maximize adaptations while minimizing fatigue. The key principles are:

  • 🏃‍♂️ 2-3 quality sessions per week plus 1 long run
  • ⚖️ Quality work comprises 20-25% of weekly running time
  • 🎯 Maintain sub-threshold state (2.5-3.5 mmol/L lactate)
  • ❤️ Keep easy runs extremely easy (max 70% max heart rate)

This calculator helps you determine appropriate paces for your interval sessions based on your current fitness level, measured through VDOT, Critical Speed, or Critical Power.
