Swiss marathon runner Franziska Rochat-Moser has announced her decision to retire after failing to fully recover from a leg injury.
The 34-year-old runner has not raced since last year's Jungfrau marathon. She now plans to run her last race at Greifensee in September.
"I have been unable to rediscover my best form since having a thigh operation last October," Rochat-Moser said. "There is no point in continuing once the enjoyment has gone."
Switzerland's most successful female marathon runner, Rochat-Moser celebrated her greatest success in 1997 when she won the prestigious New York marathon. Two years later she finished second in the Boston marathon, setting a new Swiss record of two hours, 25 minutes and 51 seconds in the process.
