Rob Hoekstra to leave as GB showjumping performance boss
Rob Hoekstra, who guided Great Britain to Olympic gold at London 2012, is to step down as British Showjumping world-class performance manager.
The British Equestrian Federation said he would be departing "to take up new challenges elsewhere in the sport".
"I believe now is a good time for a new manager to build on this success in the run-up to Rio and beyond," he said.
At last month's World Equestrian Games, Britain missed out on Olympic qualification for the 2016 Rio Games and their one remaining opportunity will come at next year's European Championships in Germany.
"I believe the sport at performance level is in a very exciting phase," added Hoesktra, a former British international rider, who will step down on 1 January. "With our existing championship riders and all the new talent coming through, the future looks very bright for continued British team success."
