Esther San Miguel Busto (born 5 March 1975 in Burgos) is a Spanish judoka.[1] She has won six national titles and two European titles for the half-heavyweight division (78 kg). She is also a bronze medalist at the 2003 World Judo Championships in Osaka, Japan, and has captured a total of twenty-seven World Cup medals, including eight golds.[2] San Miguel is a member of Centro de Alto Rendimiento Madrid Judo Club, and is coached by Sacramento Moyano.
At the 2004 Summer Olympics in Athens, San Miguel lost the first preliminary match to Great Britain's Rachel Wildin, who scored an automatic ippon in the half-heavyweight event. Despite her major setback from the Olympics, San Miguel continued to win more bronze medals at the European Championships, and was able to capture her first gold medal at the 2005 Mediterranean Games in Almería.
San Miguel was selected to compete for the third time in the women's half-heavyweight division at the 2008 Summer Olympics in Beijing. She reached the semi-final round of the event by beating Vera Moskalyuk of Russia, Brazil's Edinanci Silva, and Lucia Morico of Italy in the previous preliminary matches. San Miguel, however, was formidably defeated by China's Yang Xiuli, who scored three yuko, and an ippon in the final seconds.[3] With her opponent advancing directly into the finals, San Miguel proceeded to the bronze medal match, where she lost to France's Stéphanie Possamaï by a high-scoring waza-ari, finishing only in fifth place.[4][5]
