Held each June at the historic Chantilly Racecourse, the Prix de Diane Longines is not just a horse race; it’s an emblem of French elegance. Often referred to as the “French Royal Ascot,” this iconic event seamlessly blends high fashion, equestrian prestige, and sophisticated revelry, drawing an international crowd of style icons, racing aficionados, and luxury connoisseurs.
A Rich Heritage of Excellence

Established in 1843, the Prix de Diane has evolved into one of the most anticipated events in France’s social calendar. Dedicated to three-year-old fillies, the 2,100-metre Group 1 race showcases the finest in thoroughbred racing. Through decades of change, its core essence — celebrating equine grace and elite society — remains untouched.
Chantilly Racecourse: A Setting of Splendour
Located just 50 kilometres north of Paris, Chantilly Racecourse lies adjacent to the magnificent Château de Chantilly and its Le Nôtre-designed gardens. The venue itself feels lifted from a Rococo painting, offering visitors not only racing excitement but a journey into regal French aesthetics. VIP attendees often arrive by private car or even helicopter, further enhancing the exclusivity.
The Main Event: Racing with Refinement

At the heart of the day is the Prix de Diane race itself. Open solely to fillies, it presents a fascinating spectacle of raw power, refined training, and strategic prowess. Past winners have gone on to achieve international acclaim, cementing the race’s reputation as a springboard for greatness.
Expect a meticulously timed schedule, champagne-laced intermissions, and commentary delivered with panache. It’s where sporting excellence meets societal flair.
Fashion: The Unspoken Competition

If there’s one thing that rivals the track for attention, it’s the fashion. Hats aren’t just expected, they’re celebrated. Think wide-brimmed works of art, bespoke millinery, and gowns that echo Paris couture week. The Longines Elegance Prize adds another layer of anticipation, recognising the best-dressed attendees in a ceremony as poised as any runway show.
From celebrities in Dior to Parisian influencers in vintage Chanel, this is a masterclass in how to dress when opulence meets outdoors.
Elevated Experiences: Hospitality & Exclusivity

Premium ticket packages grant access to panoramic terraces, tailored concierge services, and unparalleled trackside views.
