Hamish Bond says he and Eric Murray scaled heights in rowing he wouldn't have dared believe.
Bond took to social media on Monday to pay tribute to long-time pairs crewmate Murray, who has announced his retirement.
It ends one of the sport's most enduring and successful combinations.
Between them, Bond and Murray were unbeaten for seven years, powering to emphatic gold medals at the 2012 and 2016 Olympics while also scooping seven world championship titles together.
Murray, 34, says his enjoyment has waned and he has decided to devote time to his family and other pursuits rather than on an Olympic campaign.
