The 3-year-old colt covered a half-mile in 50 seconds under exercise rider Martin Rivera at Churchill Downs in Louisville on Friday. Classic Empire's workmate Airoforce was timed in 52 seconds.
Norm Casse, who assists his trainer-father Mark, says it's all systems go for Classic Empire in the 1 1/2 -mile Belmont on June 10. The colt is set to fly to New York on Tuesday.
Classic Empire, who finished fourth in the Kentucky Derby, and Lookin At Lee are the only horses expected to run in all three legs of the Triple Crown. Lookin At Lee was second in the Derby and fourth in the Preakness.
Meanwhile, trainer Kiaran McLaughlin says True Timber won't run in the Belmont after being diagnosed with a fever on Friday. True Timber finished third in the Sir Barton on the Preakness day undercard and was fourth in the Wood Memorial at Aqueduct.

Other horses probable to run in the Belmont are: Japan-based Epicharis, J Boys Echo, Peter Pan runner-up Meantime, Multiplier, Senior Investment and Twisted Tom. Santa Anita Derby winner Gormley and Wood Memorial winner Irish War Cry are possible, pending workouts this weekend.
