Justify is the favorite to win the 2018 Kentucky Derby and you can watch him potentially clinch one of the most coveted horse-racing titles live online — for free.

There are 20 horses competing for the $2 million prize at the 144th annual Kentucky Derby on Saturday, May 7. Justify, a three-year-old colt who will be racing at the No. 7 post, is currently favored — with 3-1 odds — to win the 2018 Kentucky Derby. The day kicks off at 2:30 p.m. E.T. on NBC, though the big, final race isn't until later in the evening (more details on the timing of this year's Kentucky Derby are below).

The Kentucky Derby takes place at the famous Churchill Downs Racetrack in Louisville, Ky. Always Dreaming won last year's Kentucky Derby, but he failed to capture the Triple Crown title after losing at the Preakness. After the Kentucky Derby, the winner will compete for the Triple Crown title by trying to win both the Preakness and Belmont Stakes races later this summer — though only 12 horses have swept all three.

Also known as the "Run of the Roses," the Kentucky Derby is referred to as "the most exciting two minutes in sports" because the race is so short.

Here are all the details you need to know about watching the 2018 Kentucky Derby, including what time the final race starts and online streaming options:
