How to Bet on the Kentucky Derby in Colorado

With a single horse racetrack, Colorado is not a hotspot for major horse racing events such as the Kentucky Derby, Belmont Stakes, and the Breeders Cup.

However, what Colorado lacks in live horse racing it makes up for in access to betting options.

Anyone 18 or older can bet on the Kentucky Derby online or through OTBs in Colorado.

For online horse betting options, see our Colorado racebook recommendations at the top of this page.

All recommended gambling operators on this page hold valid advance deposit wagering licenses and can be accessed by visiting their respective business websites or downloading their apps to bet on iOS and Android devices.

Kentucky Derby Parties in Colorado

  • Admission: Starting at $120

The Denver Derby is the city’s biggest Kentucky Derby-themed event, spanning four blocks at 14th and Curtis street downtown. The Denver Derby claims to be the largest party of its kind outside of Kentucky, and all indications point to that claim being true.

Colorado Horse Racing FAQ

Anyone living in the Denver area has a variety of means to bet on horses legally. One option is to sign up for an account with any of the online/mobile racing betting platforms listed near the top of this page. Each is licensed in Colorado and may be accessed from anywhere in state lines.

A second option is to visit one of the several OTBs in the Denver area to place wagers in person.

Colorado law prohibits greyhound racing, but OTBs and ADWs are permitted to accept wagers on greyhound races held elsewhere.

CRS § 44-32-604 prohibits greyhound racing: “No live greyhound racing involving the betting or wagering on the speed or ability of the greyhounds shall be conducted in Colorado. The commission shall not accept or approve an application or request for race dates for live greyhound racing in Colorado.”
