New Zealand's double Olympic champion Eric Murray has announced his retirement from rowing.
The decision to end his career will mean his unbeaten record in the coxless pair alongside Hamish Bond will finish on 69 races.
Murray and Bond won Olympic gold together in a world record time at London 2012 before retaining their title at Rio 2016.
They did not lose a single competitive race across either Olympic cycle.
In addition to their two Olympic golds, Murray and Bond also won six World Rowing Federation (FISA) World Rowing Championship titles in the coxless pair, as well as one in the coxed pair.
Murray was also a member of a winning coxless four in 2007.
As a pair, Murray and Bond won numerous Halberg awards, given annually to recognise New Zealand's sporting achievements.
The duo won team of the year three times in 2009, 2012 and 2014, and the supreme award twice, in 2012 and 2014.
"I always said as long as my mind, my body and my heart were in it, then I could do this for as long as I like," Murray said in an interview with Woman's Day magazine.
"My mind's been pretty good, my body's been pretty good, but it was my heart that was on the fence.
"So, it's time to go.
"[Hamish and I] made a legacy in the sport and we got to the point where we were always winning, but it was playing on our minds and wearing us down.
"When we won a race, it was like, 'job done'.
"We didn't get that elation anymore."
