What’s your VO2 Max?
VO₂ Max Standards by Age and Gender 🏃 🏃♀️
Every runner has seen the number on their watch. Fewer know what it actually measures.
WHAT IS VO₂ MAX?
VO₂ max is the ceiling on how much oxygen your body can pull in and use when you are working hard. It is written as milliliters per kilogram of body weight per minute, which is why lighter runners tend to score higher at the same fitness.
The chart shows where the general population sits. Find your age and s*x, read across.
Two things it will not tell you. It says nothing about how long you can hold an effort, which is what actually decides a race. And it drops about 10 percent per decade after 30 if you do nothing about it, which is the part worth paying attention to.
The good news is that it responds to training faster than almost any other measure. Consistent weekly mileage moves it. So do intervals, and so does sleeping properly.
