With Doncaster’s left-handed galloping track suiting particular horses that enjoy the sweeping long straight of around four furlongs to make their winning challenge, it’s worth noting the top sires to have produced the most winners at this famous track – especially in relation to runners yet to have raced here.
Watch every race of the Betfred St Leger Festival live on Sky Sports Racing (Sky 415 | Virgin 519) from Thursday 10th to Sunday 13th September.

Top sprint sire at Doncaster (5f-6½f)
Punters who enjoy sprints at Doncaster should look out for Mehmas’ runners, as they struck over 5f-6f at 11-69 (-2) for an above A/E of 1.15 – Novello Lad the latest to represent his sire by recording a 6f double at Doncaster this summer.
Top mile sire at Doncaster (7f-1m)
When moving up a few furlongs or so to 7f-1m, then two more sires come to the fore whose progeny are worth looking out for at the St Leger meeting, namely Wootton Bassett 9-45 (+4) A/E 1.36, and Too Darn Hot 8-31 (+9) A/E 1.37.
Wootton Bassett has an interesting entry in the Champagne Stakes over 7f with Sergei Diaghilev, who is 2-3 for Aidan O’Brien - his only defeat coming when badly drawn at Royal Ascot.
Top middle-distance sire at Doncaster (1m2f-1m4f)
Lope De Vega is a stallion who produced numerous winners over 1m2f-1m4f on Town Moor, with a healthy profit to boot at 9-37 (+£20) A/E 1.29.

There are some key numbers above to look out for at the 2026 St Leger meeting, with the likes of Sea The Stars continuing to produce a high number of winners to a blind profit for punters, and his runners over 6f-1m should be noted at Doncaster.
First Season Sire
Finally, a new name to note: Persian Force.
Having already produced over 20 winners in 2026, Persian Force has quickly made a good impression with his stock.
As for which conditions his juveniles excelled, then the early signs show they improved when moved up from 5f to 6f, although he’s yet to produce a 7f winner . . .
5f: 5-58 (-39) 0.41 A/E
6f: 14-61 (+3) 1.41 A/E
7f: 0-10 (-10) 0 A/E
