From the GP website-
"Q. Will there be a turf course at the training center?
A. With the 2006 racing season, a turf course has been completed and will be available for training at Palm Meadows. The turf course will be open for training on Monday, Wednesday and Friday each week. The use of the turf course will be for breezing ONLY.
Breezing and workouts are for horses nominated to an upcoming turf stake at Gulfstream Park with the "intention" of running in a particular stake race."
