meagain Nascar drivers only turn left
Not true "Studdering John", they've had a few road course races this year too.
I agree though, moto cross racing is pretty demanding, currently Eli Tomac is a stud,
and he gets that from his dad John who used to be one of the best mountain bike racer
of his era....he was a relentless climber.
I also think NBA players, considering their size and playing with NO protective gear besides a
mouth guard, with no shift changes every minute or so (some play a full 48mins) running up and a down
a court.....These guys are some pretty tough SOB's.
