Free-runner so fast he runs upside down

Walking on water is so passé - running upside down is where it's at, as this light-footed Brit shows.

The UK free-runner has been filmed defying gravity by running a complete 360 degree loop on foot, in true Sonic the Hedgehog style.

Free-running, similar to parkour, is a form of urban acrobatics in which people perform stunts using fluid and free-flowing movements.
