'Greatest Two Minutes in Sports'

The 151st Kentucky Derby takes place tomorrow at Churchill Downs in Louisville, Kentucky. This year’s race features 20 three-year-old thoroughbreds competing in the 1.25-mile “Run for the Roses,” racing for a $5M purse, with the winner set to take home over $3M. Coverage begins at 2:30 pm ET on NBC, with the race’s post time set for 6:57 pm ET.

This year’s field includes offspring of two past Triple Crown winners and is led by favorite Journalism (3-1), who enters on a four-race win streak. He’ll face competition from Sovereignty (5-1) and Sandman (6-1), the latter drawing the historically unlucky 17th post—no horse has ever won from that gate since its introduction in 1930. Trainer Bob Baffert is also back with Rodriguez (12-1), aiming for a record seventh Derby win after a three-year suspension.

The Derby, first run in 1875, is the US' oldest continuously held sporting event and the first leg of horse racing’s Triple Crown (see 1440's overview). See how the horses got their names here.
