Our Stable

Diamond Racing Stable was established July 1, 2022 by Charlie Longo. His focus will be on developing horses for the NY Sire Stakes programs as well as importing racehorses from the UK, New Zealand and Australia. Charlie was the co-founder of Winners Circle Racing, the first fractional ownership group that he formed back in 2015.

Our Mission:

To introduce a new generation of fans and investors to the amazing sport of harness racing.   


Diamond Racing Stable recognizes the primary obstacles confronting potential owners is the cost and risk factor associated with horse ownership. Our solution is simple: offer prospective investors a "fraction" or small percentage of a racehorse that is within their budget enabling them to savor the total harness racing experience with piece of mind. Fractional ownership is an ideal way to own multiple horses at once, minimize your cash outlay and maximize your enjoyment.


Why invest with Diamond Racing Stable? 

Because it's affordable and profitable!  Horse racing was historically known as "The Sport of Kings." That is no longer the case as our stable gets you in the game for as little as 2.5%  of the purchase price. Whether you own a minimal or a majority interest, you are treated like royalty and reap all the privileges of horse ownership. We encourage investors to visit your horse at the barn, meet our trainers and enjoy the behind-the-scenes happenings in the paddock...and - with a little racing luck - pose for that memorable photo in the winner's circle.  We also host special events for owners throughout the year such our Hambletonian picnic at The Meadowlands and barn visits. It is at these events that owners can bond, exchange stories and share their passion for harness racing.

There's an old adage that says, "The outside of a horse is good for the inside of a man." Perhaps this is the reason why owning a standardbred is such a rewarding investment. Become a member of the Diamond Racing Stable family today and start creating lasting memories. Come partner with us and experience 100% of the thrills for a fraction of the cost!
