Waterland Outdoor Pursuits

A human hamster wheel. Tredalo

Chris Todd assembles his 'tredalo' 'tredalo' at Waterland Outdoor Pursuits, Lake 32 on September 12, 2012 in Cirencester, England. A man is attempting to walk across the Irish Sea - in a human hamster wheel. Chris Todd, 35, from Bromham, Wiltshire, will zig-zag 66 miles across open water for two days non-stop. He will power his metal wheel - which he calls a Tredalo - by walking on wire mesh, with two floats either side to act as stabilisers. The charity stunt will see him burn a huge 36,000 calories - almost three weeks worth - during the endurance feat. He will consume a whopping 30 litres of water and munch the equivalent of 60 Mars bars to keep energy levels up.
