THIS is the moment a daring free-runner scaled the Sage Gateshead.

Andrew Vasey performed a military-style training routine on the curved glass ceiling overlooking the River Tyne this morning (Friday, April 26).

The 18-year-old, from Washington, Wearside, spent two hours running up and down the roof, completing a parkour exercise.

He climbed up from a hatch usually used by window cleaners before performing leaps and handstands, as stunned commuters looked on.

Artist Melanie Manchot was also on the roof, videoing the spectacle for her new film, Tracer.

Commissioned by Great North Run Culture, the film features ten North-East parkour runners making their way along the course of the Great North Run.
