The purpose of the current study was to determine the accuracy of Jack Daniels' VDOT Running Calculator for the prediction of Vo(2)max, and recommendations of interval and training paces (pIN and pTH) in samples of National Collegiate Athletic Association Division 1 track athletes (ATH, n = 11) and recreational runners (REC; n = 9). Predicted variable data were obtained using results from indoor 5-km time-trials. Data from the VDOT Calculator were compared with laboratory -tested Vo(2)max, pace at Vo(2)max (Vo(2)max(pace)), and lactate threshold pace (LTpace). Results indicated that VDOT underestimated Vo(2)max in ATH (t(10) = -6.00, p < 0.001, d = 1.75) and REC (t(8) = -8.96, p < 0.001, d = 3.44). Follow-up between-groups analysis indicated that the difference between VDOT and Vo(2)max was significantly greater in REC than in ATH (p = 0.0031, d = 1.59). pIN was slower than Vo(2)max(pace) in REC (t(8) = -4.26, p = 0.003, d = 1.76), but not different in ATH (t(10) = 0.52, p = 0.614, d = 0.14). Conversely, pTH was faster than LTpace in ATH (t(8) = -4.17, p = 0.003, d = 1.49), but not different in REC (t(8) = 1.64, p = 0.139, d = 0.57). Practically, pTH can be confidently used for threshold training regardless of the ability level. pIN also seemed to be accurate for ATH, but may be not be optimal for improving Vo(2)max in REC. Practitioners should interpret VDOT with caution as it may underestimate Vo(2)max.
