Tour Dorney Lake with Britain's top sprint canoeists

Watch out for the goose poo as British sprint kayaking duo Liam Heath and Jonny Schofield, double European gold medallists, offer BBC Sport a tour of the London 2012 venue at Dorney Lake in Berkshire.

Heath and Schofield - world silver medallists this year - competed in last week's Olympic test event on the lake, which will also serve as the venue for rowing at next year's Games.
