A bottle is travelling more than 200 miles with the help of walkers, swimmers and rowers.

In a unique relay, a bottle filled with water from the Thames source, is passing through London and out to sea.

The bottle travelled from Shepperton Lock to Teddington Lock on August 30, courtesy of Dittons Skiff Club and Tamesis Sailing Club, who found time to pose for a photograph with the bottle at Molesey Lock.
