St Leger Festival: Flying Childers Stakes & Doncaster Cup Friday’s Preview

The Flying Childers Stakes is one of Britain’s notable late-season sprint races for two-year-olds, a Group 2 contest run over five furlongs on Doncaster’s straight course. Worth £130,000 in 2026, with approximately £73,723 going to the winner, it provides an opportunity for progressive juveniles to establish themselves at Group level before potentially progressing towards major autumn sprint targets.

The race takes its name from Flying Childers, the celebrated 18th-century Thoroughbred renowned for his speed. As part of Doncaster Cup Day at the St Leger Festival, the contest combines that history with a field of young horses looking to establish themselves in the sprinting hierarchy.

Pershaada brings perhaps the most eye-catching piece of Group-race form of the horses covered here. The Richard Hannon-trained filly has already won twice at Goodwood, most significantly, taking the Group 3 Molecomb Stakes over five furlongs at Glorious Goodwood in July. She won by around two lengths, with Adonius among those behind her, establishing herself as a notable juvenile sprinter.

Her earlier fourth in the Queen Mary Stakes at Royal Ascot also showed that she could compete in a major five-furlong juvenile contest. Connections then gave her a considerably tougher assignment in the Group 1 Nunthorpe Stakes at York, where she faced older sprinters on good to soft ground. She finished 14th of 18 after weakening late, but the Doncaster race represents a very different task as she returns to competition against her own age group and over the five-furlong distance at which she won the Molecomb.

Sale Shark brings useful recent form from another major summer racing festival. The Hugo Palmer-trained colt won the Listed Julia Graves Roses Stakes over five furlongs at York on 22 August, travelling behind the leaders before moving forward and taking the lead inside the final furlong. He stayed on to beat Adonius by around a length and a quarter.

That York performance followed several appearances in competitive juvenile races. Sale Shark finished fifth of 23 in the Windsor Castle Stakes at Royal Ascot, fifth in the six-furlong Rose Bowl Stakes at Newbury and fourth behind Pershaada in the Molecomb Stakes at Goodwood. His earlier debut victory at Hamilton came over five furlongs on good to soft ground, while his subsequent performances have given him experience in different conditions. The Flying Childers now provides the opportunity to move from Listed success back into Group company.

Flann Sunna has had a lighter campaign so far but has already gained experience at Group 2 level. Trained by Simon and Ed Crisford, the Blue Point colt began his career with a victory at Ascot and followed that with another success later in the summer, quickly progressing beyond ordinary juvenile company.

His most significant appearance came in the Group 2 Richmond Stakes over six furlongs at Goodwood in July. Flann Sunna travelled strongly and remained in contention approaching the final furlong before finishing a close second. It was his first experience of Group competition and confirmed his ability to compete at this level despite his relatively limited racecourse experience. Dropping from the Richmond’s six furlongs to the five-furlong test at Doncaster changes the nature of the challenge, putting greater emphasis on speed from an early stage.

If the Flying Childers is about speed, the Doncaster Cup is about stamina. The Group 2 contest is run over two miles and two furlongs and carries £150,000 in prize money in 2026. First staged in 1766, it is recognised as the oldest race still run under the rules of British Flat racing and predates both the St Leger and the Ascot Gold Cup. Its history is particularly relevant this year, as the St Leger Festival marks 250 years since the first running of the Classic in 1776.

Caballo De Mar brings proven Group 1 staying form to Doncaster. Trained by George Scott, the five-year-old has demonstrated his stamina over a range of extended distances, with his most significant performances coming at two miles and beyond.

His standout achievements include victory in the Group 1 Prix du Cadran at Longchamp in 2025 over approximately two miles and four furlongs on soft ground. He returned to Longchamp in May 2026 and added another major success in the Prix Vicomtesse Vigier, winning a tight finish over approximately 3,100 metres.

His 2026 British campaign has been less straightforward. Caballo De Mar was pulled up in the Gold Cup at Royal Ascot, after heat stress was subsequently reported, before returning in the Group 2 Lonsdale Cup at York. He travelled prominently there before weakening late to finish fourth. Doncaster’s two-mile-and-two-furlong distance gives him another significant staying assignment ahead of possible autumn targets in France.

Aidan O’Brien’s Queenstown heads into the Doncaster Cup following an encouraging return to winning form at the Curragh. The six-year-old won the Group 3 Irish St Leger Trial over one mile and six furlongs on 22 August, taking the lead more than two furlongs from home and drawing clear to score by four and a half lengths.

That victory was his first win in around 300 days and followed a period interrupted by injury, but Queenstown already had significant staying form before his latest success. He finished a close second in the Group 1 Prix Royal-Oak at Saint-Cloud in 2025 and has also performed well in elite staying company in France.

The move from the Curragh’s one-mile-six-furlong trip to approximately two miles and two furlongs at Doncaster places greater emphasis on stamina. His previous performances over extended distances, however, mean the Doncaster Cup fits naturally into his return to major staying races, adding another experienced Group performer to one of the St Leger Festival’s most historic contests.
