Scotland's national football stadium has begun its transformation into a world-class athletics arena as the countdown to Glasgow 2014 continues.
Olympic gold medallist Jessica Ennis-Hill and champion hurdler Eilidh Child became the first athletes to view the new track, which sits on steel stilts at Hampden Park.
The specialist surface will be laid next month in preparation for the 20th Commonwealth Games in July.
Ennis-Hill is expecting her first child and will not be competing at the Games but remains a high-profile ambassador for Glasgow 2014.
Child is aiming to win medals in the 400m hurdles and 400m relay event.
Glasgow 2014 chief executive David Grevemberg said: "We're really proud of what we've accomplished so far.
"To have the platform built and solution working, we are absolutely delighted.
"It has been tested and tried in the east end of Glasgow about a year and a half ago."
