My strange question would be: what would somebody with a vo2 max of 65 run their first mile in?
I remember reading an article in Runner's World talking about Frank Shorter's vo2 not being as high as you would expect from his marathon times, but attributed his times to a very high efficiency. Follows is a list of some famous runners with their vo2:
Joan Benoit Marathon runner (2:24:52) 78.6
Bill Rodgers Marathon runner (2:09:27) 78.5
Sebastian Coe Middle distance (1 mile WR) 77.0
Grete Waitz Marathon runner (WR 1980) 73.0
Frank Shorter Marathon runner 71.0
Derek Clayton Marathon runner (WR 1969) 69.7
I guess vo2 is only one of the factors in predicting race times.
