Windsor Castle Stakes 2026
The Windsor Castle Stakes is one of the most difficult juvenile races of Royal Ascot week. Run over 5f on good to firm ground, this is a speed test for lightly raced two-year-olds where early pace, draw, raw ability and the ability to cope with a big-field Ascot burn-up all matter.
This year’s renewal is headed on trends by Green Sovereign, who achieved a perfect 15/15 match, but the ratings also bring Sale Shark, Sergei Diaghilev, Celeron, Controlla, Alfred Wallace and Ruler’s Control firmly into the picture.

Final Turf Talk Filter
The final filter brings this down to Green Sovereign, Sale Shark, Sergei Diaghilev, Celeron, Alfred Wallace and Controlla.
Green Sovereign comes out on top because he is the only perfect 15/15 trends match in the race and has already shown the right blend of speed, professionalism and 5f ability. In a juvenile sprint where so many runners are still raw and developing, that profile is exactly what we want.
Sale Shark is the main danger. He has a strong 14/15 trends score, one of the better RPR figures, a solid TS number and the Hugo Palmer/Oisin Murphy combination is a major positive.
Sergei Diaghilev has the class angle. He is 14/15 on the trends and owns the highest RPR among the colts, while the Aidan O’Brien/Ryan Moore combination needs no explanation. The only question is the lower Topspeed figure.
Controlla is the ratings danger because her RPR and TS tower over the field, but the trends are not as strong and the historical filly angle tempers enthusiasm.
