Altitude performance research

Altitude can help, but it’s easy to do wrong: the constraint is quality training at reduced oxygen.

Updated Oct 17, 2026

  • • If altitude kills intensity, the benefit can disappear — protect key sessions.
  • • Use altitude strategies that fit your life: camps, intermittent hypoxia, or race-specific pacing plans.
  • • Measure what matters: RPE drift, pace drop, and recovery, not vibes.
