⛰️ Understanding Altitude Effects

🏔️ Altitude Performance Zones

  • 0-500m: Sea level - no adjustment needed
  • 500-1500m: Low altitude - 2-4% slower
  • 1500-2500m: Moderate altitude - 5-8% slower
  • 2500-3500m: High altitude - 8-12% slower
  • 3500-5000m: Very high - 12-20% slower
  • >5000m: Extreme - 20%+ slower

📈 Acclimatization Timeline

  • Day 1-3: Initial adaptation (60% benefit)
  • Day 4-7: Significant improvement (80%)
  • Day 8-14: Near full adaptation (95%)
  • Day 14-21: Complete acclimatization
  • Benefits last: 2-3 weeks after return

⚡ Performance Impact

  • VO2 max decreases ~3% per 300m above 1500m
  • Maximum power output decreases with altitude
  • Recovery time increases significantly
  • Hydration needs increase at altitude
  • Sleep quality often suffers initially

🎯 Training Strategies

  • Live High Train Low: Gold standard method
  • Interval training: More important at altitude
  • Strength training: Helps maintain power
  • Altitude masks: Limited effectiveness
  • Gradual progression: Essential for adaptation
