The Gran Premio Copa Diamante, the kind of race where absolutely anything can happen…

A full field of 20 fillies and mares will line up over San Isidro’s turf mile, with Noche Alta, Orpen Rimout, and Dream Serena emerging as the leading references in one of the most unpredictable races of the entire meeting

Absolutely anything can happen in the second running of the Gran Premio Copa Diamante (G1-1600m), the race that entered the calendar replacing the 1000 Guineas, later changed status, skipped its 2025 edition altogether, and now returns trying to finally establish some order after a chaotic beginning within the national stakes schedule.

No fewer than 20 fillies and mares were confirmed for the starting gate, an enormous field lacking any overwhelming standout and one that will almost certainly make race dynamics absolutely decisive.

Traffic trouble lurks everywhere.

This shapes as an intensely tactical affair in which decisions may carry even greater weight than usual; where a single mistake could mean defeat, while one perfect move might deliver the greatest reward.

Those intent on racing forward will need to avoid draining pace battles too early.

Those choosing to settle off the pace will face the equally difficult task of finding a clear path in the stretch—some opening in the wall of horses.

The top two finishers from the Clásico Omega (G2) will renew rivalry here.

On that occasion, Orpen Rimout (Remote) narrowly defeated Noche Alta (Hi Happy) by a head while the latter was returning from a layoff. That alone gives Noche Alta every right to believe revenge may now be within reach.

Dream Serena (Forge) finally found the finishing power she had previously lacked at this level, and she emphatically confirmed it when capturing the Clásico Paseana (G2) by 2 1/2 lengths over the aforementioned Orpen Rimout—a crucial piece of form regarding her current chances.

Another mare who typically closes from behind is Neowise (Brz-Agnes Gold), who cuts back in distance after finishing second to Miss Talento (Equal Talent) in the Clásico Juan Shaw (G2) over 2200 meters.

Still, she already owns strong performances around this mile trip, something that further strengthens her hopes.

Lessons of Life (Le Blues) defeated Dream Serena by half a head in the Fernández Guerrico (G2) before finishing fourth in the Omega, another result that reinforces just how evenly matched this field appears on paper.

Adi Shakti (Lucullan), International Look (Cosmic Trigger), and the rapidly improving Fiesta Pop (Il Campione)will all attempt to become the surprise package.

In short: absolutely anything can happen.
