What is Tapering?

A progressive reduction in training load before competition to maximise performance on race day.

Tapering is the systematic reduction of training volume (while largely maintaining intensity) in the days to weeks before a major competition. The goal is to dissipate accumulated fatigue while preserving fitness, arriving at the start line fresh and at peak performance. Research shows optimal tapers reduce volume by 40-60% over 1-3 weeks while maintaining intensity and frequency. Endurance athletes typically taper for 1-3 weeks before a marathon or Ironman; strength athletes taper 3-10 days before competition. Too much taper causes detraining; too little leaves residual fatigue.

Key points
  • Reduce volume, maintain intensity, before competition
  • Optimal: 40-60% volume reduction over 1-3 weeks
  • Dissipates fatigue while preserving fitness
  • Endurance: 1-3 weeks; strength: 3-10 days
