Fame and Glory runs in the Royal Whip, as a prep race for the Irish Champion. Rip Van Winkle may well return to 10 furlongs for the Juddmonte but he will not take on F&G in the Irish Champion if the Montjeu colt lines up.
There is nothing to stop Rip Van Winkle taking in a 10 furlong race and reverting to a mile as he did successfully last year. If Rip Van Winkle did not take in the Irish Champion then the only real alternative is the QEII.
I don't think there's much of a chance Rip will go for the QE II, especially if Canford runs (as he surely will due to his love of the course)... we'll see though.
