Fifteen horses passed the final entry phase Thursday for Sunday’s Prix de l’Arc de Triomphe, a race that is beginning to look like a sodden affair.
Tarnawa and Adayar have bounced back and forth as antepost Arc favorites, but a better draw for Tarnawa, post 3, than for Adayar, post 11, moved Tarnawa just slightly to the head of the betting markets Thursday.
