Re: 400m time guidelines
I agree with Scott. I think the posted times are pretty legit for recreational athletes (Aaron's numbers seemed best IMHO) particularly in the elite and excellent categories, but way out of whack for the untrained. For those of us who've been training for most of our lives and around similar people, the frame of reference is shockingly different than for the sedentary. There are many adult, non-diseased people out there who would be wiped after a 400m jog.
