Daniels' Running Formula

Jack Daniels on pacing and training zones, built around the VDOT number

The running coach Jack Daniels turns one race result into a full set of training paces. A single number, VDOT, comes off a recent time and maps onto easy, threshold, interval and repetition paces, plus equivalent times at other distances. Runners get a rough read on where their lactate threshold sits, without a lab test or a blood lactate meter. Coaches have used the tables for decades. Free calculators built on them are everywhere.

    Runners who cannot measure lactate directly get sent to Jack Daniels, whose VDOT number turns one race result into training paces and predicted times at other distances. The tables have been around a long time and are all over the internet, he notes.
