An investigation has been launched into the Grand National following the death of Celebre D’Allen. The British Horseracing Authority (BHA) and Aintree Racecourse will ‘analyse’ the details surrounding the fatality in a bid to make the event safer for horses.

Celebre D’Allen collapsed during the Grand National after growing exhausted. Jockey Micheal Nolan, who was later suspended for not pulling the horse up sooner, eventually stopped the 13-year-old gelding after the penultimate hurdle. Celebre D’Allen received lengthy treatment and his condition was said to be improving, but his trainers later confirmed that he died after his condition deteriorated on Monday night.

Racing authorities have previously introduced measures to make races safer for horses. The BHA reviews the Grand National event annually and Celebre D’Allen’s death will form part of their probe.

A BHA statement read: “The BHA and Aintree Racecourse will analyse the race and this incident in detail, as is the case every year and with every fatal injury in any race. This will include the horse being sent for post-mortem.

“The process of reviewing every fatality allows us to build on our existing data and help us understand how all reasonable avoidable risk can be reduced in order to keep our horses and riders as safe as possible. This process previously led to the changes that were made to the Grand National in 2024, including the reduction in the number of runners. Prior to Saturday’s race there had been no fatal injuries in the previous nine races run over the Grand National course since the 2023 National.”

Celebre D’Allen’s death was confirmed by his trainers. In a statement, Philip Hobbs and Johnson White said: "We’re heartbroken to share that Celebre D’Allen has passed away. He received the very best treatment by the veterinary teams and was improving. However, he deteriorated significantly last night and could not be saved. He was a wonderful horse and we will all miss him greatly."

An inquiry was held into the riding of jockey Nolan. Stewards subsequently banned the Irishman for 10 days.

Celebre D’Allen was one of two horses to collapse during the Grand National. Broadway Boy was leading the race when he tumbled over the 25th hurdle. His horror fall saw him tumble forward and land on his face, with jockey Tom Bellamy launched off the saddle.

Both horses received urgent veterinary attention on the course and the two later races were suspended while they were treated. Celebre D’Allen walked into a horse box and was kept at Aintree overnight. Broadway Boy walked into a horse ambulance.
