raceCoordinator looks as if its a member function of your RunProgram 
class.    using the name without parenthesis is retrieving the address 
of the function, whereas it looks as if you intended to call the 
function instead.

Incidentally, having a member function whose name is the same as the 
class except with one letter in a different case is a poor design choice 
IMHO - member functions whose names match the class should normally be 
constructors - as a casual reader of the code, perhaps not looking too 
closely, most would expect RaceCoordinator::raceCoordinator() to be a 
default constructor
