Distance runs often are used to estimate aerobic capacity. This meta-analysis of 226 correlations from 122 studies involving fixed-distance run tests produced a quantitative model of run test validity as a function of distance. Validity, the correlation between maximum oxygen uptake VO2max and running performance, increased with logarithm of distance up to 2 km. Validity was stable at r.718 for runs or 2 km. Based on these results, 2 km is an empirical minimum distance criterion for classifying a run as an endurance test. Analysis of a smaller set of 47 correlations for fixed-time run tests indicated that runs or 12 minutes had a similar correlation r.797 and should be considered endurance runs. Runs that meet or exceed these minimum distance and time criteria provide interchangeable estimates of aerobic capacity.
