What are the odds on the Grand National?
The average odds of a winning Grand National horse tend to sit around the 20/1 mark, and most winners come from outside the top handful in the market. I Am Maximus’s wins in 2024 and 2026 both came at single-figure odds, which is unusual. The majority of recent winners have gone off in double figures. Heavy weights were once thought to rule a horse out of contention, but that’s looking shakier by the year. I Am Maximus carried 11st 12lb to victory in 2026, becoming the first top weight to win since Red Rum in 1974.
Grand National Ante Post Betting Tips
I Am Maximus heads the market as he bids to become only the second horse to win the Grand National three times, following his victories in 2024 and 2026. Iroko and Jordans, who finished second and third last year, are both prominent too. Iroko in particular has now finished in the frame in both his Aintree starts.
If you’re after a new name, Soldier In Milan is the one drawing the most attention. His 16-length win in the Irish Grand National as a seven-year-old has made him second favourite for Aintree despite having no previous experience over these fences.

Grand National Experience
The Aintree fences are unlike anything else in racing. Made of spruce rather than the birch used elsewhere, there are 30 to jump across the two circuits, with the Chair and the Water Jump tackled only once and the other 14 jumped twice.
Some horses take to them straight away, yet others never quite manage it. Temperament matters as much as jumping ability. Coping with a crowd of around 150,000 people while tackling those fences at speed asks a lot of a horse. Until 2026, Tiger Roll had been the most recent multiple winner, taking the race in both 2018 and 2019. However I Am Maximus now holds that honour, and the winner from 2024 and 2026 is again expected to be targeted at the race in 2027.
Grand National Ante Post Betting FAQs
Who will win the 2027 Grand National at Aintree?
The betting market currently makes I Am Maximus the most likely winner of the 2027 Grand National, as he bids for an unprecedented third victory. Iroko and Jordans, who finished second and third last year, and Soldier In Milan, the leading newcomer, are also prominent in the ante-post odds.
Who are the most successful Grand National trainers?
Three trainers have won the Grand National four times: George Dockeray (Lottery 1839, Jerry 1840, Gaylad 1842, Miss Mowbray 1852), Fred Rimell (E.S.B. 1956, Nicolaus Silver 1961, Gay Trip 1970, Rag Trade 1976) and Ginger McCain (Red Rum 1973, 1974 and 1977, Amberleigh House 2004). Willie Mullins is closing in on that record, having trained the winner in three of the last four renewals with I Am Maximus and Nick Rockett.
