Over the decades, the standardbred breed has undergone a remarkable transformation, evolving from carriage horses to elite racehorses capable of record-breaking speeds. However, this shift towards pure speed has raised concerns about the future of harness racing, as the sport struggles to balance the demands of a changing breed with the needs of bettors and the sustainability of racetracks.

Why it matters

The standardbred's evolution from a breed known for its durability to one focused on raw speed has had a significant impact on the sport of harness racing. As records continue to be shattered, there are concerns about the long-term viability of the sport, the ability to fill races, and the appeal to bettors who may be less interested in watching horses that can no longer compete for extended periods.

The details

The standardbred breed has come a long way since its origins, tracing its lineage back to the thoroughbred Messenger. In the early days, horses like Oneida Chief, Drover, and Lady Suffolk set records in the 2:30 range. By the 1850s and 1860s, the breed had progressed to the 'two-teens,' with horses like Goldsmith Maid and Dexter setting new standards. The formation of the National Association of Trotting Horse Breeders in the 1870s helped define the breed, with horses required to meet a 2:30 speed standard to qualify for the registry. Over the decades, the breed has continued to evolve, with 2-year-olds now routinely breaking the 1:49 barrier, a feat that was once considered remarkable. This shift towards pure speed has raised concerns about the future of the sport, as the declining population of durable, long-competing horses may make it difficult to fill races and appeal to bettors.

  • In the 1830s, two pacers, Oneida Chief and Drover, made the 2:30 list.
  • In 1843, the legendary Lady Suffolk became the first to eclipse the 2:30 mark, setting a record of 2:29 1/2.
  • In 1845, the chestnut gelding James K. Polk set a new record of 2:27.
  • In the 1850s, the chestnut pacing mare Pocahontas and the roan pacing gelding Pet set records, while the legendary Flora Temple eclipsed the 2:20 mark in 1859.
  • In the 1870s, the National Association of Trotting Horse Breeders was formed, requiring horses to meet a 2:30 speed standard to qualify for the registry.

What they’re saying

“We breed no more for the likes of Su Mac Lad, Seatrain, The Grey Gladiator or Foiled Again.”

— John Berry, Author

“When the 2-year-old pacer Big Jim paced in 1:49.1 back in 2010, it was something really special. When A Rocknroll Dance did the same a year later, it was, also, really special. Then Sweet Lou went a tick faster that same year, really special. Now, today, we have 18 different 2-year-old performers that have been under 1:49.”

What’s next

As the standardbred breed continues to evolve, harness racing organizations will need to carefully consider how to balance the demands of a changing sport with the needs of bettors and the long-term sustainability of the industry.

The takeaway

The standardbred's transformation from a breed known for its durability to one focused on raw speed has had a profound impact on the sport of harness racing. While these advancements in speed are impressive, they also raise concerns about the future of the sport and its ability to appeal to bettors and maintain a healthy population of horses capable of competing over extended periods.
