Grand Slam Prize in harness racing
From 2001–2003, the Grand Slam Prize of $1 million was offered to any harness racing pacer who could win the North America Cup, Meadowlands Pace, Little Brown Jug and their Breeders Crown event.
Similarly, a $1 million Grand Slam Prize was offered in harness racing to the owners of a trotter that could win the Hambletonian, the World Trotting Derby, the Kentucky Futurity and their Breeders Crown event.
No horse was able to win either the Trotting or Pacing Grand Slam.
