The World Championship Masters were insane. I mean really, really insane. M50, M55, M60, M65, all were doing some insane times, as well as the women.
In my mind, I started thinking the possibility of some of those runners doping being pretty high, but maybe they are just good at keeping their body in pristine shape. I know I take pride and put forth great effort in maintaining my body, but I doubt I will ever run faster than sub 17 ( even 18 might be my ceiling).
I part of an elite masters facebook group, and some of the workouts and race times that they post are just mind blowing. I'm talking 50 year olds running a sub 4:30 mile and 60 years olds running around 4:55. And 40 year olds close to sub 4.
