Ruby Walsh: The microbubble of horse racing continues to defy most logic

The Tattersalls sales ring in Newmarket was a hive of activity all week as those at the top end of the sport restocked their yards for next season's action.

The seasonal crossover between Flat and National Hunt is in full swing as we await the winter stars to emerge while the summer heroes and heroines wind down, and consequently, it is hard to get super excited about the action on the track this weekend.

Billy Lee and Colin Keane are making the end of the Irish Flat season enjoyable as they battle away to be crowned champion jockey. Seventeen scheduled meetings remain between now and Naas on November 6 and, at a score of 80-79 in Billy's favour before Dundalk on Friday night, it is pretty much evens your pick. It is hard to shout for one over the other as neither do anything but impress you every time you meet them.
