Secondary school pupils took to the white water rapids of a canoe slalom course.

Children from Park High School were among 500 from across London taking part in the fourth annual Lee Valley White Water Centre Schools Festival.

The course is the one at which Team GB took gold and silver in the London 2012 Olympic Games.

Organisers of the schools festival say they hope the event will build on the legacy of the 2012 games.

On the day pupils took part in kayaking on the lake, a cycling challenge, mini tennis sessions, football sessions as well as team building activities such as the 'water wipeout'.
