Concept
Performance fitness
The current capacity to produce a race result, inferred from performances, workouts, and their trends rather than one isolated score.
Where VO2Max fits
VO2Max describes maximal oxygen-use capacity, while race-based estimates infer it indirectly from speed and duration.
Why performance is broader
Threshold, economy, durability, pacing, conditions, and motivation all influence race outcomes.
How to follow trends
Comparable races and repeatable workouts are more useful for tracking change than unlike courses or watch scores.
How to use it
Track a small set of comparable performance markers alongside recovery and training consistency.
Common misconception
An estimated VO2Max or one race result is not a complete measurement of fitness.
