I tried the Fitness Calculator and the results were not too bad.
Your VO2MAX is calculated to be 51
Your estimated “fitness age” is 32
Well, they weren’t too bad except in comparison with SB’s score, which I will not report for fear of inspiring widespread suicide among the female population. The estimated fitness age is interesting, in that I am able to hold my own in veteran’s soccer despite my advanced age, but simply cannot play with the first team the way I could back when I was actually 32.
