Four-year-old Proactif is turning heads after his smooth Irish debut that saw him win the prestigious Grade 1 National Hunt hurdle race, the Triumph Hurdle.
The Willie Mullins-trained horse was imported from France to Ireland after being purchased by JP McManus in the early Autumn of 2025, after his sole win at the Auteuil (FR).
After his performance at the Triumph Hurdle, is Proactif the new favourite to win at Cheltenham 2026? Read on to find out.
Proactif Horse Profile
Under the guidance of Willie Mullins, one of the most respected and successful trainers, Proactif is thriving.
Foaled on February 26th, 2022, the young horse has definitely proved himself so far. Bred from Masked Marvel and Balder Phenix (IRE), he comes from a lineage of thoroughbred race horses that only adds to his growing status among bettors and industry pundits.
So far, the 4-year-old gelding, now based at Carlow, has brought in $82,217 in prize money from two race wins, with his best so far arguably being at Auteuil in France. Jockeyed by L Zuliani, winning $58000.00, and beating Apolon De Charnie, it was a career-changing win (Racenet).
Form and Race Record
His form is so far faultless, winning 2/2 of the races he’s competed in and securing a reputation as the dark horse for Cheltenham 2026.
As we said, his first race was the Prix Finot (Poulains) at Auteuil in France, where Proactif won his first start by six lengths for trainer Daniela Mele. He also won on very soft ground on the day, hinting that the young horse has strong jumping ability and attitude.
Once in Ireland and under the training of Willie Mullins, he stormed out at the Triumph Hurdle with his fellow French import and stablemate, Macho Man, with a 15-8 chance to win against Macho Man’s 13-8 favourite under Paul Townend.
The race ended with those two horses battling out at the end of the two miles, with Proactif winning by two and three-quarters lengths.
Is Proactif The Dark Horse For Cheltenham 2026?
People are already talking about Cheltenham festival betting on BetMGM, and Proactif is definitely on the list. Anyone who had backed Proactif through his career so far would have got a 394% return on investment, so, naturally, people are looking at his odds for Cheltenham.
Based on early 2026 ante-post betting and reports, Proactif is heavily tipped to run in the JCB Triumph Hurdle (Grade 1) on Friday, March 13th, 2026. Considering his success on his impressive debut win in Ireland in January 2026, he’s a leading contender for the win, with the current odds at around 33/1 for the Cheltenham win.
It’s not the best and not the worst, and he is going up against big names with a track record of big wins, with names like Old Park Star and Talk The Talk sitting ahead of Proactif for the win.
That said, considering his performances so far, even though it’s a short track record, we wouldn’t be surprised if he takes his third win at Cheltenham.
Cheltenham 2026 will run from Tuesday, March 10th, to Friday, March 13th, 2026, at Prestbury Park. You’ll enjoy four days of top-tier jump racing, including:
- Champion Hurdle Day
- Ladies Day, St. Patrick’s Thursday
- The Gold Cup on Friday
