IF they aren't fit now they are never going to be in time for tomorrow's marathon 10-race card at Sha Tin. Yesterday's Sha Tin track session was all about trying to glean from their work which horses were still improving and which may have gone over the top. Geoff Lane has had a fantastic season and will be extra keen for a winner tomorrow to take him to a new personal best tally of 27. His Heavily Armed could be just the job. The strapping Irish import has been one of the most impressive of this season's crop of private purchases in his trackwork - it may even turn out that he's the best of the lot. He was going along really smoothly and clocking fast times without seeming to come under undue pressure before making a winning debut where he was drawn 11 of 11, missed the start, hung out and yet still managed to win going away from the highly progressive Manor Lord over Sha Tin's 1,200-metre trip in the style of a Class One performer in the making. Last Saturday he was noted working really powerfully under Declan Murphy, notching a very fast middle section and then forging strongly to the line without being asked a serious question. Lane is asking Heavily Armed to come back to a 1,000-metre dash down the straight tomorrow and the way he looked during yesterday's session there is no reason why it should not be well within his capabilities to score again. Heavily Armed bounded to the line in a very free 24.3 seconds looking fresh and eager to go out and compete. Alex Wong Siu-tan's Jacko has slipped down the ratings to a very handy mark and is by no means out of it in tomorrow's fifth event, particularly not on the way he ran last time and the way he worked yesterday morning. Last time out he showed a marked improvement on his more recent form to finish close up behind Optic Empire. Yesterday he underlined that he is ready to run well when clocking a most pleasing 22.7 seconds for his final 400-metre section.
