Hypothetically...........

2000 Guineas

Its very hard to narrow it down to just one race,but if we have to then for me its gotta be the Irish Champion stakes,almost always a very high class field.
BTW the St.Leger is a race I would  love to win,if I had a GNS Derby winner it would be on its way to Doncaster the second it crossed the line at Epsom.

I think it says enough i really have to agree with you on that one PD. I think my favourite one was Fantastic Lights win in 2001 agianst Galileo it was top class. I think the July Cup is also very big on my list

And Prima, if you have a triple crown winner i'll be the 1st in line to use it. A derby/leger winner is too scarey but if it hoovered up a Guineas on the way then it has to be supported. (Could it be a champion 2yo aswell please, to give me a bit more confidence)

Pot M,you think like me and yes I'd let you have him for free........well almost!you may change your mind though because if I did have a TC winner he would stay in training and then contest the Gold Cup at Ascot followed by the Prix de l'Arc,call me old fashioned but imo it would be great to have horse that could compare with the greats of long ago!I would not in the least bit care what anyone else thought he would be all mine and my pet mare would be his first mare!!!
