  • Hautacam Power: 380-450W for 35-38 minutes (6.2-6.8 W/kg)
  • VO2max Utilization: 85-92% for entire final climb
  • Lactate Threshold: At or above LT2 for 30+ minutes
  • Core Temperature: Can exceed 39°C despite altitude
  • Altitude Effect: 3-5% power reduction at 1,520m
  • Energy Systems: 95% aerobic, 5% anaerobic for attacks

Training for HC Climbs

To excel on climbs like Hautacam:

  • Threshold Work: 3x20min at 95% FTP
  • VO2max Intervals: 5x5min at 110-120% FTP
  • Long Climbs: 60-90min steady efforts
  • Altitude Training: 3-4 weeks at 2000m+
  • Heat Adaptation: Sauna protocol 3x/week

Test your climbing readiness with our FTP test and lactate threshold assessment.
