We're taking to the rapids and the stunning white water of the River Tay, near Aberfeldy. This is the spiritual home of Scottish paddling and the Premier Canoe Slalom, one of the most important races of the season. Olympic gold medallist, Tim Baillie from Aberdeen, gives an expert's view on the action. Also in this programme, we're swapping paddles for pedals as we join the UK's only extreme unicycle team and Cameron McNeish discovers a lunar landscape of breath-taking beauty on a Wild Weekend.
