in his words
Well this was an interesting way to spend my Wednesday morning! Wanted to see my fitness level ahead of my events the rest of the year, then compare afterwards - love data me! Got 55 ml/min/kg, which apparently puts me in the top 10% for my age and gender 😲 wtf! Fully Bane-mode with the mask, and felt good - but need to work on my running form at high speeds apparently!
