Whether you know a little or a lot about horse racing, it’s always fascinating to watch the betting markets chop and change when a major race, like the Grand National, is on the horizon.
Horses who, on the face of it, don’t look like they could mount much of a serious challenge are suddenly in contention as their odds continue to shorten. That is what has been happening to Senior Chief, Henry De Bromhead’s 8-year-old bay gelding in the days leading up to April 5th 2025.
Despite odds tumbling from 50/1 to 25/1 in recent weeks, questions remain about whether he has the form and stamina to triumph in the world’s most famous steeplechase. They’re still good odds, especially if you use your Grand National free bets to back him.
That way, you can support Senior Chief’s bid without risking your own money, giving you the thrill of cheering for a potential dark horse while maintaining a sensible approach to betting.
So let’s do a quick deep dive into his career, recent performances, and the legacy of his trainer to assess his chances.
A Mixed Bag of Promise and Challenges
Senior Chief began his career with promise and has had a couple of significant wins over the last couple of seasons. His lifetime earnings of £92,603 reflect a solid record but not one that screams dominance.
His best performance came last October at Cheltenham, where he won a competitive handicap chase over 3m1f on good ground while sporting first-time cheekpieces.
However, his form has been inconsistent. Last time out, he finished ninth in a handicap hurdle at Naas, beaten by 15 lengths on heavy ground. Back in November, he was sixth in a Grade 3 chase at Newbury over 3m2f, again struggling to keep pace with the leaders.
These results raise concerns about whether he can handle the demanding 4m2f Grand National distance, especially when he pulled up in the Irish National last year, and that race is shorter than Aintree.
The Case for Senior Chief’s Grand National Bid
All that said, there are reasons to believe Senior Chief could surprise at Aintree. His Cheltenham win demonstrated adaptability and resilience on good ground – qualities that could serve him well if conditions are favourable.
Trainer Henry de Bromhead has expressed confidence in his left-handed preference and ability to improve with experience. Furthermore, Senior Chief’s weight allocation of 10st10lb is manageable compared to top-weighted rivals like I Am Maximus (11st12lb), giving him an advantage in stamina preservation.
Additionally, De Bromhead’s decision to target the Grand National shows strategic intent. The trainer has emphasised that the race has always been in his plans for Senior Chief, even after a disappointing Irish Grand National attempt last year where he was pulled up.
His pedigree also suggests potential stamina reserves; sired by Gentlewave (IRE) out of Absalom’s Girl (GB), Senior Chief is bred for endurance.
Concerns About Form
Despite these positives, there are valid doubts about whether Senior Chief can deliver on the big day. Moreover, his tendency to fade late in races raises questions about his ability to navigate the demands of 30 fences over more than four miles.
His lack of consistent top-tier performances against elite competition also sets him apart from favorites like Intense Raffles (7/1) and I Am Maximus (10/1), both proven winners in major races.
While that doesn’t necessarily rule him out – 2016 winner Rule The World had never even won a race before the Grand National – Senior Chief still has some question marks over stamina.
He fits some trends of past Grand National winners—age, weight, and experience; however, he lacks standout achievements that would make him a clear contender.
Why Are His Odds Shortening?
Sometimes, even if a horse hasn’t won many races, people might hear that he’s been training really well or that his trainer thinks he’s improving.
This can make people believe that the horse has a better chance than they thought, so they start betting on him more.
When many people bet on the same horse, the bookmakers want to make sure they don’t lose too much money if the horse wins. So, they lower the odds to balance things out.
A Trainer Who Knows How to Win
Henry de Bromhead’s reputation adds credibility to Senior Chief’s bid. Based in Knockeen, County Waterford, de Bromhead is one of Ireland’s leading trainers.
His career highlights include winning the Grand National with Minella Times in 2021, a historic victory with Rachael Blackmore as the first female jockey to win the race.
De Bromhead has also claimed multiple Grade 1 victories across Cheltenham Gold Cups and Champion Hurdles. His ability to prepare horses for high-stakes races is unmatched, and his partnership with Blackmore remains a potent combination heading into Aintree.
Whether Blackmore will ride Senior Chief or stablemate Minella Indo remains undecided but could influence betting markets significantly.
Should We Pay Attention to Senior Chief?
Senior Chief is undoubtedly an intriguing outsider for the Grand National. His falling odds reflect growing confidence among punters and the belief that de Bromhead can unlock his full potential.
However, skepticism remains due to inconsistent form and questions about stamina over extreme distances.
While he may not be among the favourites, Senior Chief’s manageable weight and flashes of brilliance make him worth considering as a dark horse capable of springing a surprise.
With de Bromhead’s expertise guiding him and cheekpieces sharpening his focus, there’s a compelling narrative building around this gelding.
