Irish trainer Aidan O'Brien celebrated a podium sweep after Found won Europe's most prestigious horse race, the Prix de l'Arc de Triomphe, at Chantilly Sunday. The four-year-old Irish filly, saddled by Ryan Moore, kicked with four furlongs to run to convincingly win the Arc, the richest race in Europe with five million euros ($5.6m) in total prize money. Highland Reel and Order of St George came in second and third to round off an outstanding day's racing for O'Brien, whose sole previous Arc victory was by Dylan Thomas nine years ago. Pre-race favorite Postponed came in fifth. Reaching speeds of up to 60kph over the tricky 2.4km (11⁄2-mile) Chantilly track, hosting the race while Longchamp undergoes much-needed renovations, Found was not among the early pace-setters led by Vedevani, touted Japanese runner Makahiki and Highland Reel. Order Of St George, ridden by Frankie Dettori, moved up into second behind Vedevani with The Grey Gatsby third and Postponed wide in fourth being tracked by Left Hand and Makahiki. But as the horses hit the home stretch in perfect conditions at the racetrack north of Paris, Found accelerated through the jostling field along the inside rail with Highland Reel on her coattails and found herself with a free run-in to the line. Found's victory ended a run of five successive runner-up spots in Group One races including being beaten by Postponed in the Coronation Cup at Epsom in June. But the filly had run a superb prep race for the Arc in finishing second in the Irish Champion Stakes in September. "It's the most special race of the year!" Found's jockey Moore beamed of the Arc. The Arc is currently the third richest race in world after the Melbourne Cup ($6.2 million) and Dubai World Cup ($10 million). It will be the fourth from January when the first edition of the $12 million Pegasus World Cup will be run at Gulfstream Park on Jan. 28.
