Are you going for Red Rum's record then pjr?
4 in a row would be unbelievable
I have won it once with a grey called Sand Cat but that was on SO3, it had tried about 5 times before it finally won and that was a 4M4F horse, had to retire it to stud after it won because I wanted to breed it with another 4M4F horse.
Are you going for the 4 pjr?
