Unbanned G Polytrack -
The original version targeted 1.8G sustained. The new "Unbanned" spec has been dialed back to a still-respectable 1.65G sustained, with peaks at 2.0G. This brings it into legal alignment with current GT3 specifications but retains the aggressive ramp-up characteristic that drivers fell in love with.
So, why has the "unbanned G Polytrack" become the headline of the year? Following intense lobbying from the Time Attack World Championship and a complete reformulation of the compound, the governing bodies issued Revision 4.7 of the Technical Directive.
Here is what the new, legal "Unbanned G Polytrack" offers:
Yes, with caution.
The updated surface is safer than the original G formula, but not identical to Tapeta or straight dirt. Best practices:
To understand the "unbanning," you must first understand the chemistry. Standard Polytrack (the "MX" or standard formula) is a mix of silica sand, recycled rubber, spandex fibers, and a wax coating. It behaves like deep, forgiving dirt.
The "G" formula (short for "G-Plus" or "Granular" depending on the patent) was a reaction to a specific problem: heat and migration. unbanned g polytrack
In the mid-2000s, trainers complained that standard synthetic tracks became "dead" in the summer heat. The wax would soften, and the rubber fibers would migrate to the top, creating a loose, "kicked-back" surface that horses hated. Martin Collins, the manufacturer, developed the G variant. This formula replaced the traditional wax with a specialized polyurethane and gel binder. The "G" track was harder, faster, and theoretically less weather-dependent.
Why it was initially "banned": Between 2007 and 2012, tracks like Keeneland and Del Mar experimented with Polytrack. The "G" variant, however, showed alarming stats. While it reduced catastrophic breakdowns (fatal fractures), it doubled the rate of non-fatal soft tissue injuries—specifically proximal suspensory desmitis (PSD). Veterinarians noted that the "G" surface was too firm under the top layer. Horses ran fast, but their lower limbs absorbed shock like they were running on asphalt covered in carpet. By 2014, racing commissions in California, New York, and Kentucky unofficially "blacklisted" the G formula, demanding traditional dirt or the safer "Tapeta" surface instead.
Riders reported inconsistent kickback, “sucking” down at the heels, and unpredictable energy return. Several top trainers publicly refused to run horses on G Polytrack, effectively banning themselves from using it. The original version targeted 1
The landscape of horse racing has changed drastically. Three factors are driving the push to unban G Polytrack:
1. The Mortality Crisis Despite a return to dirt, the equine fatality rate has plateaued. The Jockey Club reported 1.32 deaths per 1,000 starts in 2022-2023 on dirt—numbers that activists find unacceptable. The "unbanned G Polytrack" offers a statistical lie: some tracks using the new unbanned formula report a 70% reduction in fatal breakdowns compared to dirt. Regulators are now willing to trade suspensory strains for catastrophic deaths.
2. Climate Resilience The original "G" was banned partly because it dried out too fast. However, the new unbanned formula (sometimes called "G2" or "Unchained G") uses a hydrogel polymer that retains moisture. In an era of drought and extreme heat (Churchill Downs, 2024), the ability to maintain a consistent "cushion" without watering is a massive operational win. To understand the "unbanning," you must first understand
3. The "Fiberlogic" Innovation The old "G" failed because the fibers were recycled and short. The newly unbanned version uses bi-component fibers (nylon core/polyester sheath). These fibers stand vertically in the cushion. They don't compress into a hard pan like the old G did. This single change has made trainers, who once boycotted the G, re-evaluate.
The “G” formula was more sensitive to temperature and moisture. Improper harrowing or wax levels led to a “cushion deadening” effect — too deep or too firm.
