@john1954moi I don't fully understand the age grading. My wife (who is much fitter than me) is a shade under 60% but my absolute best is 46.6%. I appreciate I'm on the precipice of the next age category, but does that mean that I am in poor shape compared to literally the rest of the planet? It only identifies 60% as 'local level' so presumably under this is 'rubbish level'?
