The idea of [[VDOT]] is at the heart of [[Jack Daniels Running Formula]]. To find out your [[VDOT]] and associated paces, you will need the results of a recent race into the VDOT Calculator form below. This will give you a series of equivalent times for other distances. It will also give you a list of paces for various workout types and distances. As well as being a 'VDOT Calculator', it is also a 'FIRST Calculator', as it lists the paces for the [[FIRST]] training program.

Note: you must enter the time of a race you have completed, not your target time for a race. Please repeat out loud "I will enter the time of a race I've completed". More seriously, this is a very common mistake that you need to avoid. Train based on your current fitness, not the fitness you hope to achieve. If you put in a target pace rather than an actual pace you are missing the point of the system. Jack Daniels paces are intended to provide a pace that produces a specific training stress. If you don't use a previous race pace, you will be using the wrong pace.
