Guy’s been pushing himself to the outer limits, as usual. There's no medals, no big ceremony at the end of it all. He's just driven by putting himself through the misery. And coming out smiling. In search of suffering, Guy went to Colombia for the TV job, where he was kidnapped, tortured and shot at. He's also been to the Arctic to join the Royal Marines at their winter training centre, taking on the most James Bond exercises he's ever done while still seriously injured from a motorbike crash that knocked him unconcious. Off the telly, Guy's gone on two epic bike rides, spanning over a dozen countries, led by his sat nav along multi-lane motorways and up remote goat tracks, sleeping on the roadside. He's been to Mablethorpe Beach, the destination for racing things that shouldn't be raced; he's entered one of the toughest motorcycle endurance events in the world (twice); and he's been working on the '300mph job' - that's the world record he's going for and he's building a bike to get him there. Read on, and let Guy Martin take you with him on his travels to the brink.
