As the name suggests, you lug a spouse over a rugged 250-metre course, with the fastest time winning. To ensure fairness, there is a minimum wifely weight of 49 kilograms. Clearly this atavistic pursuit struck a chord, as there is now a North American championship along with the annual world championship in Finland.
Noted carriers include Dennis Rodman, who "borrowed" a wife for the 2005 world titles. Prizes are generous, with the champion receiving the wife's weight in beer, and, intriguingly, "a bag full of wifecarrying products".
