The 43-year-old Castille thinks he's capable of running 2:15.

Castille already ran 1:04:45 and got a USATF letter saying he qualified, but then without notice his name was taken off the list because the course wasn't record eligible. Castille: “It really pisses me off. It’s nonprofessional. It kind of makes me angry. It’s not something [USATF] should put me through.”
