Chris Todd, 35, hails from Bromham, Wiltshireman in the UK. Todd is attempting to walk , yes walk...across the Irish Sea – in a human Hamster Wheel. He plans to zig-zag 66 miles across open water for two days non-stop. He will power his journey with a metal wheel – which he calls a Tredalo – by walking on wire mesh, with two floats either side to act as stabilizers. The charity stunt will see him burn 36,000 calories – almost three weeks worth – during the endurance feat. He will consume a whopping 30 liters of water and munch the equivalent of 60 Mars bars to keep energy levels up. And unlike Lance Armstrong, he says no doping is allowed!
