Aidan O'Brien Biography

Aidan O'Brien is one of the most popular and richest Horse Trainer who was born on October 16, 1969 in County Wexford, County Wexford, Ireland. During the off season Johnny Murtagh was appointed stable jockey after Kieren Fallon’s acquittal on race-fixing charges was quickly followed by a second drugs suspension. However the introduction of Johnny Murtagh to Ballydoyle was to prove a baptism of fire and assisted Aidan in what was to be a vintage Ballydoyle year, equalling his previous best Group 1 tally of 23. As a team Aidan and Johnny were to dominate the Irish classic scene taking all five Irish Classic Races thus being the first trainer to do so since 1935. He again was named Champion trainer in Britain taking his second title in a row. He equalled former Ballydoyle resident Vincent O’Brien’s record of 6 winners at Royal Ascot, four of these at the highest level including Yeats’ record-equalling third consecutive Ascot Gold Cup. Henrythenavigator won both the Irish and English 2000 Guineas, and followed up with the St James’s Palace Stakes. Duke of Marmalade won 5 times at group 1 level and was considered by many to be the Champion older male horse in Europe at middle distances. Other highlights through the year were provided by Halfway to Heaven, Frozen Fire, Mastercraftsman, Mount Nelson, Fame and Glory, Septimus and Moonstone.

O’Brien set a new world record by training 26 Group or Grade 1 winners in one calendar year when Saxon Warrior won the Racing Post Trophy at Doncaster, which beat the US-based Bobby Frankel’s 2003 mark of 25. By the end of the year O’Brien extended the record to 28.

Kieren Fallon replaced Spencer as Ballydoyle’s stable jockey. On the first classic weekend of the 2005 flat season the newly formed partnership of Aidan O’Brien and Kieren Fallon took home both the 2,000 Guineas (Footstepsinthesand) and the 1,000 Guineas (Virginia Waters). More major successes followed with Oratorio (Eclipse Stakes, Irish Champion Stakes), Scorpion (Grand Prix de Paris, St. Leger) and juveniles George Washington, Rumplestiltskin and Horatio Nelson.

The end of the 2006 season had apparently left Ballydoyle with multiple options for the following year’s classics. However the opening part of the season was left in turmoil after the premature retirement of Holy Roman Emperor. The previous year’s champion miler George Washington proved almost infertile, ultimately siring only one foal. As a late replacement, Holy Roman Emperor was sent to Coolmore Stud. Plans had to be drastically changed with O’Brien saying “all our eggs were in one basket” in relation to the opening classic of the season the 2,000 Guineas. As a result, the season began relatively quietly as far as O’Brien’s classic crop was concerned. However signs of changing fortunes would emerge on the day of the Poule d’Essai des Poulains when Astronomer Royal came with a late run to give Ballydoyle a 1–3–4 finish. Group 1 success was seen in the older horses through the previous year’s Irish Derby winner Dylan Thomas when he won the Prix Ganay. The mid summer was highlighted by Scorpion winning the Coronation Cup in an O’Brien 1–2 with stable mate Septimus. The stable also dominated the St. James’s Palace Stakes and the Irish Derby with Excellent Art and Soldier of Fortune respectively leading home 1–2–3 for O’Brien horses. O’Brien finished Royal Ascot as top trainer with four winners including Yeats who retained his Ascot Gold Cup and Henrythenavigator who set the juvenile standard for the early part of the season by winning the Coventry Stakes. Kieren Fallon returned to retainer duties in both Ireland and France, although his ban in Britain was still being enforced pending the result of his trial in relation to fraud in racing. Peeping Fawn managed to learn from her second place in The Oaks by taking the Audi Pretty Polly Stakes at the Curragh and eventually overturning form, albeit on softer ground, with Light Shift in the Irish Oaks. The season of 2007 also saw Aidan land the one big European race that had so far eluded him throughout his illustrious career when Dylan Thomas won the Prix de l’Arc de Triomphe under Kieren Fallon. The season however ended on a very sad note after George Washington was put down after breaking down in the Breeders Cup Classic.

Aidan O’Brien is married to Anne-Marie (née Crowley). Anne-Marie’s father, Joe Crowley trained horses at Piltown, County Kilkenny, where his tenure was interrupted in quick succession by his daughter Anne-Marie (Champion National Hunt Trainer during her brief time at the helm), his son-in-law Aidan O’Brien (who took over from his wife in 1993 but moved on to Ballydoyle in 1996) and then another daughter, Frances Crowley (who moved on to train on the Curragh for some years). Joe then renewed his own training licence for some years before retiring.

The start of the 2006 flat season saw George Washington confirm his juvenile promise by easily winning the 2,000 Guineas on Newmarket’s Rowley Mile to give O’Brien his fourth win in the race. While George Washington disappointed in the Irish equivalent, he redeemed himself in the Queen Elizabeth II Stakes at Ascot. Dylan Thomas also made his mark in the top middle distance races in Europe. After going close in the Epsom Derby, he was found to be more effective under a patient Kieren Fallon ride in the Irish Derby. Dylan Thomas also showed his battling qualities in the Irish Champion Stakes, where he beat the Champion mare Ouija Board by a neck. Other 2006 highlights came through Alexandrova who dominated the middle distance fillies classics taking in The Oaks, Irish Oaks and Yorkshire Oaks. The end of season saw the juvenile Holy Roman Emperor take the Prix Jean-Luc Lagardère on Arc day at Longchamp. In one of the races of the season he was beaten by a head in the Dewhurst Stakes by European Champion 2-year-old Teofilo. Much anticipation centred on the expected rematch of these two colts in the 2,000 Guineas at Newmarket the following spring. Aidan finished the season with prizemoney of over €6.5m in Ireland and Great Britain. The season was marked however by the emerging race fixing allegations involving stable jockey Kieren Fallon. On 3 July 2006, Fallon was charged along with 7 other people for conspiring to defraud clients of the internet betting exchange Betfair. Fallon was one of 28 people answering bail at Bishopsgate police station in the City of London in connection with the inquiry. In a released police statement, he was described as being charged with “offences relating to allegations of fixing the outcome of horse races between 1 December 2002 and 2 September 2004, and money laundering”. He was amongst three jockeys charged, along with Darren Williams and Fergal Lynch, all of whom had their licences to ride in Britain suspended, effectively under the principle that they would be guilty until found innocent. Fallon’s problems were further compounded when on 29 November 2006 the French racing authority France Galop suspended Fallon for six months after he tested positive for a metabolite of a banned substance.
