When is the horse racing season in the U.S.?
There really is no horse racing betting season in the U.S.
Racing occurs virtually year round on many racing circuits, moving from one track to another to add some variety.
Christmas Day may be the only day of the year when there isn’t a single racetrack running in the U.S. (though Camarero Race Track in Puerto Rico was open for business on that day in 2019 and likely will be again this year).
In other words, even if your local track isn’t conducting racing, you likely have lots of opportunities to wager on contests being conducted elsewhere, including in other countries.
