Colorado's one racetracks — addresses & live cards
Bally's Arapahoe Park · 26000 E Quincy Ave, Aurora, CO 80016
Colorado's only live racetrack, running a roughly 31-day meet across the summer and fall with Thoroughbred, Quarter Horse and Arabian racing. Anchors a statewide network of 10+ OTB locations operated by Mile High Racing & Entertainment.
Signature stakes races at Colorado's tracks
Beyond the everyday cards, each Colorado track hosts at least one feature stakes race that draws statewide attention — most are bettable through every ADW listed above.
Mile High Derby
Arapahoe Park's headline Quarter Horse event and the centerpiece of the live meet, paired with the Mile High Futurity for two-year-olds.

Part of the Emirates Breeders Series for Arabian horses — a one-mile contest for three- and four-year-olds reflecting Arapahoe Park's ties to Abu Dhabi racing.
Who regulates horse racing & sports betting in Colorado
Colorado uses two separate regulators for horse racing and sports wagering — each licenses operators independently.
CO Division of Racing Events (Dept. of Revenue)
Horse racing and pari-mutuel wagering are regulated by the Division of Racing Events within the Colorado Department of Revenue. Online ADW betting is legal statewide for bettors 18 and older. A recent change also lets licensed sportsbooks offer fixed-odds horse racing. Greyhound racing has been banned since 2014, though OTBs and ADWs may still accept simulcast greyhound wagers from other states.
CO Limited Gaming Control Commission
Voters approved sports betting via Proposition DD in November 2019; online and retail wagering launched in May 2020 under the Limited Gaming Control Commission. Colorado runs one of the most competitive markets in the country, with 25+ licensed online operators, and permits wagering on in-state college teams. Minimum age 21; you must be physically inside Colorado.
How to Bet on Horse Racing
New to the windows? Start with the straight bets. A win bet needs your horse to finish first; place pays if it runs first or second; show pays for first, second or third. They are the cheapest way to learn the game.
From there come the exotics, where the real payouts live. The exacta asks for the first two home in order, the trifecta the first three, and the superfecta the first four. Multi-race bets — the daily double, Pick 3, Pick 4 and Pick 6 — string winners together across races, and the Pick 6 jackpot can roll into life-changing money. Our guide to exotic bets walks through each one, and the beginner’s guide to betting on racing covers the basics end to end.
