Europe’s most prestigious middle-distance crown is up for grabs this weekend. On Sunday, 4 October the racing world will turn its eyes to France for the running of the iconic Group 1 Qatar Prix de l’Arc de Triomphe.

Boasting a massive €5 million prize pool, this historic 2,400-metre turf spectacular at ParisLongchamp Racecourse remains the definitive world championship of flat racing.

Whether you are placing an ante-post punt or soaking up the Parisian glamour, here is everything you need to know about the 2026 renewal.

A century of turf history

Inaugurated in 1920 to celebrate the allied victory in World War I, the “Arc” has grown into the ultimate test of speed and stamina. Its roll of honour is a gallery of turf immortals, featuring legends like Sea-Bird, Dancing Brave, Treve, and the magnificent Enable.

Winning the Arc doesn’t just secure a massive payday; it guarantees a permanent place in racing folklore and monumental breeding value.

The grand stage – ParisLongchamp

Set against the backdrop of the Bois de Boulogne, ParisLongchamp is a beautiful yet notoriously tricky right-handed track. Its defining feature is the famous fausse ligne droite (false straight), a sweeping, deceptive bend before the real 400-metre run-in.

Veteran jockeys often speak of the unusual silence that falls over the back stretch, requiring exemplary tactical patience before “pressing the button”.

The blockbuster 2026 field

While the final declarations drop later this week, the preliminary field is shaping up to be an international heavyweight clash:

  • The Defending King: Last year’s brilliant winner, Daryz, heads the entries. Trained by Christopher Head, he recently bounced back to his best with a smooth victory in the Prix Foy at Longchamp.
  • The Challenger: Juddmonte’s star mare, Kalpana, is officially aimed at the Arc instead of the Royallieu. The King George VI and Yorkshire Oaks champion is operating at a higher level than ever.
  • The Rising Stars: The English Derby standout Maltese Cross and Aidan O’Brien’s elite fillies add spectacular depth to the three-year-old vanguard.

Betting angles and favourites

According to latest bookmaker prices, Daryz sits as the firm 7/4 favourite to achieve back-to-back immortality. However, at that short price, many sharp punters are looking for value elsewhere.

Maltese Cross (5/1) and Kalpana (7/1) represent massive threat levels. Kalpana, in particular, looks like excellent value if she turns up in peak form, given her proven versatility to win on any ground.

Trackside tips and insights

The inside scoop from the Parisian training yards hinges on two major variables: the draw and the weather.

  • Watch the Rain: Clerk of the course conditions look stable, with officials expecting “bon souple” (good to soft) ground. If unexpected autumn downpours hit Paris, it will severely disadvantage faster ground specialists and bring a horse like Bay City Roller right into play.
  • The Draw Ceremony: France Galop has introduced a brand-new electronic draw format this year. The stalls will be drawn on Thursday morning, 1 October, but kept under lock and key until a glamorous evening reveal ceremony. Keep a close eye on this, a wide draw at Longchamp can ruin a horse’s chances before the gates even open.
