Arc 2026 Weekend: ParisLongchamp Hosts Racing's €5M Sunday

The first October weekend in France belongs to horses. The 105th Qatar Prix de l’Arc de Triomphe runs Sunday afternoon at ParisLongchamp — 2400 metres of turf, €5 million on the table, the richest and most famous race in European flat racing. A two-day meeting (Oct 3–4), a defending champion back to keep his crown, a rule change that rewrote the entry list, and a city running its fashion week and its transport strike at the same time. This is the France guide to Arc weekend 2026: the race, the contenders, and how to get to the Bois de Boulogne when the metro is on strike.

The race: Sunday afternoon, 2400m, €5M

The Arc is run over 2400 metres on the turf of ParisLongchamp, a Group 1 for three-year-olds and up, on the first Sunday of October — this year Oct 4, mid-afternoon. The purse has held at €5 million since 2021 (a statement of stability while other European races inflated): €2.857M to the winner, €1.143M second, €571.5k third, €285.5k fourth, €143k fifth, plus breeder premiums of €135k to the winning breeder. Winning the Arc is about far more than the cheque — it makes stallions and defines legacies — but the numbers explain why the world’s best thoroughbreds, jockeys and trainers converge on the Bois de Boulogne. The Saturday card opens the meeting; Sunday is the day the world watches, live on ITV1 in Britain and across the racing channels worldwide — with the parade ring, the lawns and the weighing-room lawn all working as one great open-air salon.

The defending champion: Daryz

Last year’s Arc was a classic: Daryz staged a late run to snatch victory from hot favourite Minnie Hauk in a photo finish, winning by a head. The four-year-old son of 2009 champion Sea The Stars added two more Group 1s at Longchamp over shorter trips this season, ran third at Royal Ascot on ground probably too quick for him, and confirmed his wellbeing by winning the Qatar Prix Foy on Sept 6 — the traditional Arc trial. He heads the entries and the conversation. The danger list is long: Minnie Hauk back for revenge (though winless in her last two), unbeaten three-year-old filly Diamond Necklace (French Oaks winner, stamina the question), French Derby winner Constitution River, and Kalpana — the five-year-old mare who won this summer’s King George and evokes Juddmonte’s 2024 winner Bluestocking. Around 73 horses hold entries ahead of final declarations.

The rule change: geldings admitted

On Sept 4, the European Pattern Committee approved opening the Qatar Prix de l’Arc de Triomphe to geldings — the first time in the race’s 105 runnings. It matters for the shape of the field and the philosophy of the race: some of the best middle-distance horses in training are geldings, and their absence had been an increasingly debated quirk. New names entered the ante-post lists within days (Thundering On prominent among them), and the final field on Sunday will look different from any Arc before it. If you only remember one fact for the dinner table: this is the first Arc where geldings can run.

Getting to Longchamp mid-strike

ParisLongchamp sits in the Bois de Boulogne, west of the 16th — not on the metro, strike or no strike. Race days run shuttle buses from the city side; the rail option is RER C to Avenue du Président Kennedy plus the walk through the Bois; the green option is a bike via the Bois paths (Vélib’ stations line the park edges). With the CGT walkout open-ended since Monday 7pm and RER A/B degraded, the shuttles and RER C are your backbone — check the RATP and SNCF apps the morning of, leave an hour earlier than instinct says, and treat the walk through the Bois as part of the day (autumn colours, coffee stands, the crowd building). Gates open well before the first race; the Arc itself runs mid-afternoon, with the supporting Group 1s stacked around it.

Saturday: the undercard and the hats

Don’t sleep on day one. Saturday’s card at ParisLongchamp is a Group 1 festival in its own right — the traditional trials and supporting championships that set up Sunday’s narrative: which three-year-olds stay on, which jockeys arrive in form, which stables are talking. The crowd is smaller, the lawns are calmer, and the prices (entry and food) are kinder — regulars call Saturday the connoisseur’s day. It is also hat day in practice: millinery spotting peaks on Saturday when the photographers outnumber the form students. Arrive for the early races, walk the parade ring between contests, and stay for the last — by Sunday you’ll read the track like a local. Two-day badge holders get the full arc of the weekend, literally and figuratively.

The Sunday that has everything

Oct 4 is that rare Paris day when the city offers three different worlds at once: the Arc at Longchamp (sport, hats, picnics on the lawn — bring food, the queues are part of it), Paris Fashion Week’s Sunday — Lacoste 10:30am, Miu Miu 1pm, Valentino’s return to Paris 3:30pm, Mugler 6:30pm — and the first full October Sunday in the museums and parks. Our suggested split: runways in the morning (livestreams count), RER C west at lunch, Longchamp for the afternoon card, and the Arc as the week’s sporting exclamation mark. Toussaint is 32 days away; autumn starts here.
