Top British Contenders to Watch in 2026 Randox Grand National

British trainers arrive at Aintree with cautious optimism after years of Irish dominance in the Randox Grand National. Filmogaz.com assesses the likely home contenders and their chances ahead of declarations next week.

Recent trends and context

Irish-trained horses have largely dominated recent renewals. In April 2025 Irish yards supplied the first three home, and the first four finished that year.

Corach Rambler provided Lucinda Russell with a Scottish victory in 2023. Since Many Clouds led the English 1-2-3-4-5-6-7 in 2015, Ireland has won repeatedly.

Field size and qualification

The published top-40 contains 34 guaranteed runners and six reserves at final declarations. Several British hopefuls sit on the fringe and need withdrawals to gain a starting berth.

Five British candidates are priced 20/1 or shorter in antepost markets. That group underlines the select nature of the credible home hopes.

Top British Contenders to Watch in 2026 Randox Grand National

Haiti Couleurs

Trained in Pembrokeshire by Rebecca Curtis, Haiti Couleurs is a notable non-Irish runner. The nine-year-old won this season’s Coral Welsh Grand National.

He travels with strong handicap-chase form and would handle further rain. Sean Bowen is the likely pilot for Aintree.

Panic Attack

Dan Skelton’s mare has a 5-9 strike-rate over fences. She has won two major handicap events this season.

Panic Attack occupies the final qualifying slot on the current list. She now carries 12lb more than when she won the Paddy Power Gold Cup.

Twig

Paul Pauling’s veteran won a Sandown handicap in November. He then edged out Mr Vango to win the Becher Chase.

Twig’s rating rose by 3lb after the Becher. He currently needs other withdrawals to make the Aintree line-up.

Mr Vango

Trained by Sara Bradstock, Mr Vango finished second in the Becher. He has failed to complete his two subsequent starts.

He pulled up after backing out of the race at Newcastle’s Eider, raising questions over his current fitness.

Iroko and Jagwar

Both owned by JP McManus, the pair are trained by Oliver Greenall and Josh Guerriero. They offer contrasting styles.

Iroko is a grinder who finished fourth in a past National. Jagwar is a smoother traveler, rated officially 5lb well-in inside the top 34.

Johnnywho

Trained by Jonjo O’Neill and A J O’Neill, Johnnywho ran prominently in the Ultima at Cheltenham. He sits just outside the current qualifying positions.

Officially 6lb in hand relative to his mark, he still needs withdrawals to secure a starting place.

Longer-priced British hopes and wider picture

The Real Whacker, Marble Sands and Beauport remain long-priced. Each carries questions over form or exposure.

British trainers performed well across the spring, including clean sweeps in Cheltenham’s handicaps. The key test is whether Aintree will host a home winner.
