Let's work an example with a hypothetical runner who completes a marathon in 3:10 and weighs 220 Lb. A marathon time of 3:10 is a [[VDOT]] value of 50, which we will assume is also a [[VO2max|V̇O₂max]] of 50. A [[VO2max|V̇O₂max]] of 50 means you consume 50 ml of oxygen per Kg of body weight per minute. If you weigh 220 Lb, which is 100 Kg, and your [[VO2max|V̇O₂max]] is 50, that equates a total Oxygen consumption of 5000 (ml/min). Reversing the equation above, 200 Lb is 91 Kg and 5000 / 91 is a [[VO2max ]] of 55. A [[VDOT]] of 55 equates to a marathon time of 2:56. That's a reduction of 14 minutes in marathon time. The [[VDOT Calculator]] will work out this for you.
