This year's Preakness Stakes will go down in history because it's the 150th anniversary of the iconic horse race. It's also the final time the race will be held at Pimlico Race Course. Nine, three-year-old thoroughbreds will compete for the honor of winning the "Middle Jewel" of the Triple Crown.

Four of the nine horses in this year's Preakness field -- including Journalism, Sandman and Clever Again -- ran the Kentucky Derby. The other one was American Promise, which will try for a better showing following a 16th-place finish at Churchill Downs.

This will be the final horse race at the track ahead of demolition and a major reconstruction project, which will impact Pimlico and the surrounding Park Heights neighborhood.
