Aiming to be the best VDOT calculator, it this will generate [[VDOT]] and [[FIRST]] training paces, predicted race times with adjustments for temperature, body weight and altitude.

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 * This calculator 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. * You may have several race results that indicate different VDOT values. If the races are all reasonably recent and reflect your current fitness level, use the best VDOT number. If you've been injured or had a break from training since your last race, you should not use an old race result. * This VDOT Calculator will also attempt to compensate for races run in hot conditions. This is based on the research documented at [[Impact of Heat on Marathon Performance]] and is an estimate only. If you enter your weight, the VDOT Calculator will predict your race performances at different body weights, assuming the weight change is due to body fat only. * If you provide your greatest weekly distance, this calculator will output the long runs for the Jack Daniels marathon plans.
