Crawling through the dirt beneath barbed wire or through tunnels of old tires. A 15-kilometer dash through the clinging mud of Wolverhampton, near Birmingham. Splashing through icy water at the end of January: Welcome to the Tough Guy Race. But even tough guys work better together. The contest is a magnet for hard-bitten teams from universities and corporate enterprises: The more willing they are to help one another to conquer the course, the better their chances of winning.
