IRON BUTTERFLY runs in a mare maiden hurdle race at Catterick tomorrow and she has a decent chance. There are 15 runners but it looks an open contest on paper. She ran well on her hurdling debut, finishing fourth at Sandown, and has gone the right way since then.The ground will suit her as she likes cut in the ground and at the moment the going is soft. The only slight concern is the course as it is a sharp track and she is a big long striding filly. If she handles the track you can see her running a big race tomorrow.
