to be the 1999 Arc winner Montjeu, who had won eight of his last nine starts, including six Group Ones, and was described as being "on the verge of immortality". Montjeu was made 4/5 favourite ahead of Sinndar at 6/4, with the unbeaten German colt Samum, and the Prix Vermeille winner Volvoreta the only other runners to start at less than 25/1. Sinndar led in the very early stages, before settling into second behind his pacemaker Raypour. Murtagh sent Sinndar past Raypour and into the lead at the start of the straight. Several horses attempted to challenge, with the filly Egyptband looking the biggest threat to the leader, but Sinndar stayed on to win by one and a half lengths. It was three lengths back to Volvoreta in third and a further two and a half lengths back to Montjeu in fourth. Murtagh was effusive in his praise of Sinndar's speed and stamina, saying, "No horse can get by him... he's the best horse... unbeatable". However, Montjeu's trainer, John Hammond, observed that "You always think there's going to come a day when they don't quite fire and that happened today". Feeling that the colt had "nothing left to prove", Sinndar's connections announced his retirement ten days later. Race record Assessment For his performances in 2000, Sinndar was voted European Champion Three-Year-Old Colt. Curiously, he was then beaten in a separate poll for the Cartier Horse of the Year title by a rival three-year-old colt, the miler Giant's Causeway. In the International Classification (the forerunner of the World Thoroughbred Racehorse Rankings) Sinndar was named the best three-year-old in the world and the second best racehorse of in 2000 with a rating of 132, two pounds behind Dubai Millennium (134) and five pounds ahead of Giant's Causeway. Sinndar was given a Timeform rating of 135 following his Arc win. Stud career After being retired from racing, Sinndar stood at the Aga Khan's two main studs moving between the Haras de Bonneval in Le Mesnil-Mauger in Lower Normandy, and the Gilltown Stud in County Kildare. He sired the winners of more than 200 races including Shawanda (dam of Encke), Youmzain and Rosanara (Prix Marcel Boussac) and Shareta finished second to Danedream in the 2011 Arc. Sinndar's son, Sinnbad has also been to Royal Windsor Horse Show and Horse of the Year Show for ROR Showing, as well as winning many area dressage finals
