Aim. Many previous studies have examined the time limit at which an individual can maintain V.O2max (Tlim V.O2max) during high-intensity continuous and intermittent runs to exhaustion. The main purpose of the present study was to examine the effects of employing different criteria used in previous investigations during Tlim V.O2max evaluation. Methods. Seven moderately trained competitive runners completed 2 running tests to exhaustion, during which metabolic data was obtained from breath-by-breath gas analysis. The 1st test was an incremental test to evaluate V.O2max and the minimal running velocity at which V.O2max was elicited (v V.O2max). The 2nd test was a continuous single velocity test at v V.O2max from which the time to attain V.O2max (TA V.O2max) and Tlim V.O2max were subsequently evaluated. Time at V.O2max was evaluated employing 6 specific criteria. Intra-individual differences in Tlim V.O2max values due to applying the different criteria were analysed using a one-way ANOVA, with significant differences between pairs identified using Tukey’s HSD posthoc test. Significance was set at p
