TWO teenagers from Bolton will appear on television tonight to reveal the truth behind their favourite “sport”.

Marshall Davies and Richard Sue, both aged 16, aim to prove that parkour is a legitimate sport, rather than just daredevils jumping off roofs.

A broadcast production team has been following the group’s work for a special feature, which will be shown at 6pm tonight on ITV’s Granada Reports.

* Parkour is described as running while attempting to negotiate obstacles in the most efficient way possible, such as by jumping and climbing.
