A straightaway chute leads on to the backstretch of the Main Track and permits races on the dirt up to long to be run with one turn. The chute used to extend further back across the training track, permitting races of up to a mile and a quarter, but was shortened because a crossover is now infeasible given the clay base of the Main Track and stone-dust base of the training track. Before the 1990 Breeders' Cup, the outer rail of the Main Track was moved back to widen the middle of the clubhouse turn and soften the angle of the start of the Classic. The training track is in circumference and abuts the east end of the main track. In March 2009, lights were added to the training track as a safety measure to prevent early morning workouts from occurring in the dark.
