Are At the Races themselves do any publicity for the game, lending there name to it youd hope so. Maybe contact them, they have a pretty good website.

Worth trying i suppose would be the Racing Post, the national daily racing paper over here in the UK, also all the big book making chains, William Hill, Ladbrokes, Coral. All the above have excellent websites.

I'll keep thinking, if I think of any more will let you know.
