vVO2max (velocity at maximal oxygen uptake) is an intense running pace which can be maintained for only about six minutes. This is the minimum speed for which the organism’s maximal oxygen uptake is reached (after a few minutes of exercise at this intensity); at higher paces, additional power is entirely delivered by anaerobic processes. At this pace, blood lactate in the muscles reaches levels around 8-10 mM.
The vVO2max of world class middle and long-distance runners may exceed 24 km/h (14.9 mph or about 4:00/mile pace), making this speed slightly comparable to 3000 m race pace. For many athletes, vVO2max may be slightly slower than 1500 m or mile race pace.
