If I may butt in. And repeat myself from earlier.
La Bague Au Roi has no chance in the JLT or RSA,
Gordon & Willie have at least half a dozen who will prove better, And then there's the other Irish Trainers on top of that. Not to mention Mr Henderson over here.
If they insist on going to cheltenham then she would have a better chance in the four miler IMO as the big gun trainers will tend not to send there strongest horses to that race.
She would have a good proven amateur jockey available I think - and the travelling thing can only ever be a positive, irrespective of the distance IMO. If you're of the opinion she won't relax and is a bit keen then it'll cost her over any distance, the trainer should be able to deal with that anyhow.
