These times are not fast at all. Humans evolved to run. If there are elite athletes running sub 5 for 26.2 miles, then it would be fair to say most males' quickest mile would be one measly sub 5. I find it difficult to believe somebody can be so genetically inferior as not manage that. Sub 60 is not that fast either. Talent doesn't start playing a part until the low 50s.
I know 90% of you are about to type "I'm in my late 40s and have not managed a sub 5 or sub 60 min 5k after 10 years of hobby jogging!"
