Septimus run on-hold Trainer Aidan O'Brien will walk Flemington's track on the morning of Tuesday's Melbourne Cup before giving Septimus the all-clear to run. Connections of the Irish St Leger winner had earlier in the week expressed fears the ground might be too firm for their star stayer. The Ballydoyle handler walked a lap of the track on Monday and branded conditions as "fast" ahead of the Group 1 handicap over 2m. "We didn't come here to watch from the grandstand," O'Brien told www.sportal.com.au. "It's fast ground, the track's in unbelievable order and we know the guys are doing everything in their power to produce a safe track. "I don't want to be going on about ground. "All I'm worrying about is I want to have Septimus when he goes home." O'Brien, who also runs Honolulu and Alessandro Volta in the Melbourne Cup, assessed the track with course manager Mick Goodie. Goodie said: "To him he says it's fast ground, but what he calls firm or fast ground and what we call fast ground is completely different."
