UK Athletics (UKA) chief executive Niels de Vos will step down at the end of September, following more than a decade in the role.
During de Vos' 11-year tenure, the national governing body delivered the successful IAAF World Championships and World Para Athletics Championships – as well as establish athletics as one of Britain's most successful sports at the Olympic Games.
Under his leadership, Team GB won 13 medals, six of them gold, at both the London 2012 and Rio 2016 Olympics.
"Niels has been a fantastic servant to not only UK Athletics, but the sport of athletics as a whole," said Richard Bowker, chair of UKA.
"The sport has grown and been hugely successful under his leadership and Niels leaves with our enormous thanks and we wish him well for the future."
De Vos is leaving to set up his own business and Bowker revealed that UKA will retain de Vos' services in a "limited capacity", in order complete a "number of important issues" where he has led discussions and negotiations.
Nigel Holl, UKA’s strategy and partnerships director, will assume the role of Interim CEO until a permanent replacement is appointed.
