Aiden O'Brien Breeders Cup Horses Training at Santa Anita

The Aiden O'Brien contingent returning from a work on Santa Anita's synthetic track Wednesday morning (Oct. 22). Shown here are (left to right) Red Rock Canyon, Duke of Marmalade, Henrythenavigator, and Soldier of Fortune .

Henrythenavigator and Duke of Marmalade are entered in the $5 million Breeders Cup Classic, and Red Rock Canyon and Soldier of Fortune will run in the $3 million Breeders Cup Turf -- both races to be run this Saturday as part of the 2008 Breeders Cup World Thoroughbred Championships at Oak Tree Santa Anita.

The international shippers seem to be acclimating well to the seasonally warm Southern California weather. Temperatures during early morning training hours have been in the 60's, and days warming up to the mid-90's with clear, very dry conditions.
