Swiss sprinter Matthias Rusterholz has decided to end his running career at the age of 29.
The 400 metres specialist has been plagued by injuries for the last four seasons and recently had to pull out of the Sydney Olympics after tearing a tendon during training.
The Berne-based Appenzeller won five national titles in the 400 metres and still holds the Swiss record for the discipline. His finest career achievement came in 1994 when he won bronze at the 1994 European Championships in Helskinki.
Since 1995 he has been a regular member of the Swiss 4x400 metres relay team, with whom he finished fifth at the 1998 European Championships.
