Three-time Olympian and later longtime coach Horst Karsten was a West German eventer. At the 1964 Tokyo Olympics, representing the mixed German team, he won a team bronze medal and finished sixth in the individual event. Four years later at Mexico City, then representing West Germany, he placed fifth with the team and 11th individually as the best West German rider. Finally, at München in 1972, he won his second bronze with the team, although he did not finish the course.
Karsten also claimed one bronze at the Worlds (1974 team), and five more at the Europeans (1965, 1973, 1977 individual; 1969, 1975 team). He also earned one silver with the team in 1977, and a gold in 1973. In 1963, 1965, 1973, 1977, and 1981 Karsten won the West German Championship. From 1986-2000 he was head coach of the (West) German eventers. In 1964, Karsten was awarded the Silver Bay Leaf, the highest German sports award. In 2007, he was the first German to be inducted into the Hall of Fame of the International Association of Three-Day Event Riders.
