Hmmm...
On my environment (Linux, Ruby 1.8 HEAD, Tcl/Tk 8.4.7), 
it seems working properly.
Maybe it fails to update widgets on your environment. 
Please try to add 'Tk.update' at last of the callback.

> w.menu.bind('<MenuSelect>') do
>   entry_var.value =
>     if option_var.value == 'Marathon' then '26.2'
>     elsif option_var.value == '10K' then '6.2'
>     else '0'
>     end
      Tk.update  # <== HERE
> end
