Suk believes he is leaving British archery in good shape ahead of 2012
Peter Suk, the South Korean head coach of Archery GB, has announced he is to leave his post after four years.
Suk, 54, will head home after the World Cup Grand Final in Copenhagen on 26 September, where he will be supporting Britain's Simon Terry and Nicky Hunt.
"I have had a wonderful time working in Britain, but I think the time is right to go home to my family," he said.
"There is three years until 2012 and I hope I've laid foundations for British archers to win medals in London."
He added: "There are some very talented archers in this country who are already established among the best in the world, and we have some very good youngsters coming through, so it is an exciting time."
Suk was appointed in May 2005 after 14 years working in Italy, and headed up the launch of the Archery GB Performance Unit.
Under his guidance, British archers have featured in every World Cup Grand Final since the competition was launched in 2006, winning three medals at the World Championships in Leipzig two years ago.
He has also supported the Paralympic team, who brought home four medals in Beijing, and four more from the recent World Championships in the Czech Republic.
David Sherratt, the chief executive of Archery GB, said: "Peter has made a marvellous contribution to the continued development of archery in this country, and we are sad to see him go.
"The marvellous results we have had at so many tournaments around the world speak for itself, and the progress we have made reflects on the excellent job he has done."
Sara Symington, who took over as performance director of Archery GB earlier this year, said: "I have only been involved for a few months, but I have learnt so much from Peter in such a short time.
"His legacy to British archery is immense - he revolutionised the coaching and preparation of our archers, from diet to fitness to technique.
"He will be a hard act to follow, but we will make sure we find the right person to build on the foundations that Peter has put down, and that we are among the likely medal winners at Lord's, during the London Olympics."
