I am 68 years old and use to run regulary since the teenage. I use to get around 43,44 which gives me a condition age in the thirteens :-). For a few week ago I noticed that value start to appear on days I did train in it. Today I got 47 which give me 29 years condition age while I didnont trained today. As far as I know it should be a run at least 15 min to get a avalue. Anyone with the same issue or know why this happning. Ofcourse I have nothing against being 29 again :-;).
