Does VO2 Max Really Matter?

Published:

We hear a lot about different training metrics, including the most famous of all: VO2 Max, the maximum amount of oxygen you are able to use during intense effort. It’s been suggested that VO2 Max is the ultimate measure of fitness and predicts our longevity, but is it really something most of us should focus on when designing a training plan? As explained in this piece by pro-athlete, Becky Wade Firth, “It doesn’t account for competitive instincts, mental fortitude, closing speed, running form, fueling strategy, technical skills or any of the other hard-to-measure variables that also play an important role in your running performance and potential.”


“I had a good day and I’m just really pleased with myself,” So states Natalie Grabow, an 80 year old athlete who just became the oldest woman to finish the Kona Ironman World Championship. Natalie started triathlon at 60, when she finally learned to swim, and her daughter proudly explains how her mother is an “example of what working hard and sticking with something and riding out the highs and lows. You just keep going. You never give up.”
