Look Here (horse)
Look Here (foaled 28 February 2005) is a British Thoroughbred racehorse and broodmare best known for winning the 2008 Epsom Oaks. In a racing career which lasted from October 2007 to October 2009 the filly ran nine times and won two races. After winning her only race as a two-year-old, Look Here finished second on her three-year-old debut. She then won the Classic Oaks over one and a half miles at Epsom, in which she was a 33/1 outsider. Look Here never won another race, but finished third in the St Leger Stakes, Coronation Cup and Pretty Polly Stakes.
