Some info I read about the breeding of Empire Maker and Funny Cide and their potential to go the distance:
"Empire Maker, a high-class colt, eventually will add to his Grade I wins (Florida Derby and Wood Memorial). But no offspring of his esteemed dam, Toussaud, has won a Grade I race on dirt beyond 1 1/8 miles,,,"
"Funny Cides speed and pace numbers at 1 mile and 1 3/16 miles suggests a mismatch, and a maternal family that includes two Belmont winners stamps him as one horse in the field to whom 1 1/2 miles will pose no problem."
That sounds about right since I love Empire Maker at 4-1.
Best of luck!
