serious danger and came home five lengths clear of Glad One with Pandora Bay a short head away in third. Her win was the first major success for Boutin, and led to his stable attracting many leading owners and top-class horses over the next three decades. Having won over one and a half miles at Epsom La Lagune was dropped back in distance for the Prix de Diane over 2100 metres at Chantilly Racecourse but ran poorly and finished unplaced behind Roseliere. After a two-month break she produced a better effort on her return as she came home third behind Roseliere and Pola Bella in the Prix Vermeille. In her last two starts the filly was matched against world-class male opposition and ran creditably as she finished fifth in both the Prix de l'Arc de Triomphe and the Washington, D.C.International. Breeding record At the end of her racing career, La Lagune became a broodmare for her owner's stud but produced only one known foal: Rose du Kentucky, a bay filly, foaled in 1970, sired by Bold Lad. Won one race and produced Alchimiste who won 13 races in the United States. She was also the grand-dam of Trishyde, who won the Prix de Malleret in 1992. Assessment and honours In their book, A Century of Champions, based on the Timeform rating system, John Randall and Tony Morris rated La Lagune an "average" winner of the Oaks.
