Three days. Eleven Grade 1 races. One of the greatest races in the world. The 2026 Aintree Grand National Festival opens on Thursday 9 April, and while the eyes of the world are fixed on Saturday’s Randox Grand National, the opening day card is no mere warm-up act.
Four Grade 1 contests are scheduled across the afternoon. Each one carries the form threads that underpin the statistical analysis the TradeOnSports approach is built on. Here is the data edge guide to Aintree Opening Day 2026.
Race 1 — 1:45pm: Boodles Anniversary 4-Y-O Juvenile Hurdle (Grade 1, 2m1f)
The juvenile hurdlers kick off proceedings, and this renewal carries genuine quality. Three of the leading protagonists are coming directly out of the Triumph Hurdle at Cheltenham, a race that by this point in the season represents the definitive form guide for four-year-old hurdlers.
The key runner: Selma De Vary heads the market at 5-2, with Maestro Conti (11-4) and Minella Study (4-1) completing the Triumph triumvirate. Both Winston Junior and Mange Tout (4-1 and 6-1 respectively) add depth.
The analytical lens on this race: Aintree’s 2m1f on an end-of-season card tests stamina more than Cheltenham’s 2m in March. Horses that handled the pace of the Triumph well tend to strip fitter here, but ground conditions often play a decisive role in re-ranking the form.
Race 2 — 2:20pm: William Hill Manifesto Novices’ Chase (Grade 1, 2m4f)
This race has produced several future stars, and the 2026 renewal is no exception. Lulamba is the dominant market leader at 4-7, a significant favourite price in a Grade 1, having finished third in the Arkle Chase at Cheltenham. Lulamba’s short-priced favouritism reflects the strength of Nicky Henderson’s training operation and the horse’s clearly superior form line.
Koktail Divin (7-2) is the most significant challenger, with Jax Junior and Mambonumberfive (both 8-1) completing the principal market.
The data case for Lulamba: A horse that finishes in the frame in the Arkle at Cheltenham, the premier novice chase test of the season — and then shortens up significantly for Aintree is being backed by the market to confirm superiority. The 4-7 price reflects exceptional confidence, but history cautions that Grade 1 novice chases rarely play out as neatly as favourite prices suggest.
Race 3 — 2:55pm: Aintree Bowl Chase (Grade 1, 3m1f)
The feature race of the afternoon in terms of senior chasers, and the one with the most compelling form line. Jango Baie finished second in the 2026 Cheltenham Gold Cup, the championship race for staying chasers, and now reverts to slightly shorter than Gold Cup distance for the Bowl.
The market makes Jango Baie the 4-5 favourite. The field is completed by Impaire Et Passe (9-2), Spillane’s Tower (5-1) and Protektorat (13-2).
Jango Baie’s Cheltenham form is the class reference for this race. A horse that ran to the level of winning a Gold Cup needs only to perform to that level to be exceptional over 3m1f at Aintree. Whether the slight drop in trip suits or hinders depends on whether his finishing effort at Cheltenham was stamina-driven or tactical.
Race 4 — 4:05pm: William Hill Aintree Hurdle (Grade 1, 2m4f)
The final Grade 1 of the day, and a rematch of the Champion Hurdle principals. The New Lion (7-4F), Brighterdaysahead (2-1) and Alexei (8-1) finished second, third and fourth at Cheltenham’s Champion Hurdle — an elite form reference point. El Fabiolo (5-1) and Golden Ace (12-1) add further market depth.
This is the most statistically interesting race of the day from a form-revisionist perspective. The Champion Hurdle result is the definitive quality benchmark. But Aintree at 2m4f in April is a different test from Cheltenham’s 2m in March — more stamina-testing, often less frenetically paced.
The analytical question: which of the Cheltenham finishing order benefits from the extra quarter-mile? Brighterdaysahead’s form profile, second at Cheltenham, may suit Aintree’s more staying test better than the sprint finish Cheltenham rewards. The New Lion’s favouritism is earned, but the gap in the market between 7-4 and 2-1 is narrow enough to suggest the race is genuinely contested.
