The English flat season begins in earnest at Newmarket on the first weekend of May. The Guineas Festival — Saturday 2 and Sunday 3 May — stages the first two British Classics of 2026: the 2000 Guineas (colts) and the 1000 Guineas (fillies), both run over a mile on the Rowley Mile course.
2000 GUINEAS 2026: KEY CONTENDERS
The 2000 Guineas is the first Classic of the British flat season — a Group 1 over one mile for three-year-old colts. The prize fund exceeds £500,000 and the winner is immediately installed as a leading contender for the Derby at Epsom in June.
THE MARKET LEADERS
Ruling Court (Aidan O'Brien, Ryan Moore) — 7/2 favourite
Aidan O'Brien has won the 2000 Guineas a record eleven times. Ruling Court was his champion juvenile in 2025, winning the Dewhurst Stakes at Newmarket in October — the most reliable trial for this race. Dewhurst winners have an extraordinary 2000 Guineas record: five of the last ten Dewhurst winners went on to win the Guineas.
Ryan Moore, who knows the Rowley Mile better than any jockey alive, is confirmed. Ruling Court has a high cruising speed and is drawn in stall 5 — an ideal berth on good ground.
Why he can win: The Dewhurst form is the gold standard. O'Brien targets this race above all others. Moore's tactical skills on the wide Rowley Mile are unmatched.
Risk: He has not run since October. That is a 195-day gap. History shows that colts returning after more than 180 days without a prep race win the 2000 Guineas less than 10% of the time.
Shadow of Light (Charlie Appleby, William Buick) — 4/1
Godolphin's Shadow of Light won the Middle Park Stakes at Newmarket in September, beating subsequent Group 1 winners in a fast-run race. Charlie Appleby has won two of the last five 2000 Guineas (Coroebus in 2022, Native Trail in 2021) and his preparation methods are proven.
Shadow of Light ran in the Craven Stakes at Newmarket on April 16 — finishing a close second to a 50/1 outsider on his seasonal debut. Appleby described the run as "exactly the blowout he needed" and the Craven has been a reliable 2000 Guineas trial in recent years.
Why he can win: Race-fit after the Craven. Proven at Newmarket. Appleby's Classic preparation is formidable. Buick knows how to ride the Rowley Mile.
Risk: The Craven defeat raises questions about whether he has trained on. Did the outsider beat him on merit, or was it genuinely a prep run?
Henri Matisse (Aidan O'Brien, Seamie Heffernan) — 8/1
O'Brien's second string — but that label can be misleading. Henri Matisse won the National Stakes at the Curragh in September and has physical scope to improve. He is bigger and rangier than Ruling Court, which historically points to a horse who will be better at three than two.
Why he can win: O'Brien often wins the Guineas with his improver rather than his Dewhurst winner. Henri Matisse has more physical development to come.
Risk: Untested at Newmarket. The Rowley Mile demands a specific blend of tactical speed and sustained acceleration that not every Irish-trained colt possesses first time.
Each-Way Contenders
Alyanaabi (John & Thady Gosden, Oisin Murphy) — 12/1
The Gosdens' Alyanaabi won the Autumn Stakes at Newmarket in October. He is bred to be a miler (by Dubawi out of a Frankel mare) and has the pedigree for this race. At 12/1 each-way he offers the best value in the upper market.
Rashabar (Kevin Ryan, Daniel Tudhope) — 16/1
A northern-trained outsider with a live chance. Rashabar won the Coventry Stakes at Royal Ascot in June 2025 and has been trained specifically for the Guineas since. Kevin Ryan knows how to prepare a horse for Newmarket and Tudhope is one of the most underrated jockeys in the weighing room.
