Cheltenham Festival 2027 Antepost Hub: Star Sports and the Corporates

Cheltenham Festival 2027 — the dates

Tuesday 16 – Friday 19 March 2027. Four days, 28 races, roughly £7m in prize money, the high watermark of the National Hunt racing calendar.

Key early-2027 antepost contenders

As of April 2026 research, leading antepost positions across the Championship races:

Gold Cup — Gaelic Warrior a clear market leader around 3/1 following his 2026 Cheltenham Gold Cup win. Likely rematch with Fact To File. The field shape will evolve through autumn trial form.

Champion Hurdle — Lossiemouth the ante-post favourite around 3/1 after winning the 2026 Champion Hurdle. Constitution Hill still entered despite his 2026 Cheltenham and Aintree falls. Brighterdaysahead likely the principal new challenger.

Ryanair Chase — Fact To File likely back for a tilt after the Gold Cup route, with Lulamba at 8/1 as a strongly touted alternative.

Supreme Novices' Hurdle — Mydaddypaddy among several fancied novice contenders.

Mares' Hurdle — Air of Entitlement flagged by Timeform.

These are April 2026 snapshots. Expect significant market moves through:

• Autumn trials at Carlisle, Wetherby, Ascot, Punchestown (October–December)
• Christmas Festival at Kempton (Boxing Day)
• Dublin Racing Festival at Leopardstown (early February)
• Trials up to Festival week

Star Sports is the one book here with NRNB standing year-round as a published rule rather than a seasonal promotion. For the other four, the standard ante-post rule at all of them is that a stake is lost if the horse doesn't run: NRNB on ante-post bets is something each firm switches on for a limited window close to declarations, not a permanent term, so "NRNB on Championship races" for those four means "runs one when the promotion is live," not "always on."

The Star Sports proposition for 2027 Cheltenham

Where Star Sports wins:

• The four Championship races (Champion Hurdle, Queen Mother Champion Chase, Stayers' Hurdle, Gold Cup) — NRNB applies and early pricing is typically competitive with Bet365.
• Published £100,000 antepost ceiling — transparent and known.
• Phone trader desk access at 0800 052 1321 for antepost bets at size.

Where Star Sports loses:

• The 24 Cheltenham Festival races outside the four Championship races — no NRNB, traditional rules, non-running horses cost the full stake.
• Handicap extras (Coral Cup, Pertemps, County Hurdle, Plate, Kim Muir, Grand Annual, Ultima, Martin Pipe, Fred Winter) — no enhanced place terms.
• Welcome offer: the BET40GET20 free bets must be placed at 4/1 or bigger and expire 24 hours after credit, which rules out most ante-post use. They carry no accumulator requirement.

The portfolio play

For a serious 2027 Cheltenham antepost punter, the recommended portfolio structure:

Primary NRNB book: Bet365. Deepest markets, NRNB runs across the card once the promotional window opens, biggest racing investment.

Secondary NRNB book: Paddy Power for Cheltenham handicap extras once its NRNB window is live. William Hill is a close alternative.

Specialist book: Star Sports for the Championship races + phone-desk access at size + transparent £100k cap.

Exchange cover: Betfair Exchange or Matchbook for liquidity on the biggest markets, especially Gold Cup and Champion Hurdle, where exchange depth is good.

Antepost market timing

October–November 2026 — markets open, early prices typically best for Gold Cup and Champion Hurdle.

December 2026 — first significant trial form. Christmas Festival at Kempton moves the book.

January 2027 — Dublin Racing Festival 1 February–2 February moves Irish-trained ante-post positions significantly.

February 2027 — final declarations approach for the Festival. Trial form settled; NRNB windows typically fully active.

March 2027 — Festival week. Declarations finalise 48 hours before each race.
