The underdog - Joshua Davis

Joshua Davis had a dream. He dreamt of being the best. It didn't really matter what he was the best at, he just wanted to be number one, the big enchilada, to say that he had made it. This is how it began: Josh was driving through the Mojave Desert one day when he saw a sign for the American arm-wrestling championship - all comers welcome. He decided to enter. He came fourth, out of four, but this was enough to secure him a place on Team USA and the chance of a show-down with the 'Russian Ripper' at the world championships in Poland (that didn't end very well either).

But Josh had tasted the dizzy rush of competition and wanted more. And more turned out to be the most outlandish contests in the world - from bull fighting in Spain and backward running in Italy, to sumo wrestling and the World Sauna Championship in Finland.

Joshua's quest is by turns hilarious, harrowing and a little insane, but it is also inspiring - because, after all, every underdog deserves his day.
