How to Calculate Altitude Performance
What is Altitude Performance?
At altitude, reduced atmospheric pressure means less oxygen per breath. VO2max decreases approximately 1% per 100m above 1,500m, causing slower pace for the same perceived effort.
Step-by-Step Guide
- 1VO2max reduction: approx 1% per 100m above 1,500m elevation
- 2Performance impact is greater for longer, more aerobic events
- 3Acclimatisation over days to weeks partially compensates through physiological adaptations
