Slightly off-topic, (after being thinking about this) speaking in terms of things I would personally change in Irish racing, I think it doesn't have a great pattern to it's season and would like HRI to look at improving this. The 2 year old pattern is good, but for 3 year olds and above, it's quite poor - no mile Group 1, no top sprint races, no 1m4 group 1 (yet 2 at 1m2).
Also, they could look at the atmosphere at Irish courses/facilities etc.
Longchamp for the Arc meeting is as good as flat racing gets - I'm not saying this is easily replicated, but if a racing weekend in France can draw 10000 British racegoers, there must be the potential for Irish racing to do something similar, albeit on a smaller scale.
They have a race in the shape of the Irish Champion which is a real jewel, but they could look at having that, the National Stakes, the 1m fillies race, Irish Leger etc on 1 day/1 weekend. This might address the paucity of french runners in these races as well, and market the weekend as a mini-championship weekend.
