The contest is rooted in the legend of Ronkainen the Robber, said in the 19th century to have testing aspiring members of his gang by forcing them to lug sacks of grain or live animals over a similar course.
Another theory is that it stems from an even earlier tribal practice of wife-stealing.
In honour of this, many contestants now take up the challenge with someone else's wife.
This year, as in the four previous years, the winning couple was Finnish pair Taisto Miettinen and Kristiina Haapanen.
The most popular method of carrying the women is called the 'Estonian' method.
Wrapping the women's legs around the man's head and hanging upside-down behind them, it was allegedly inspired by how Eastern Europeans use to carry their women - at least according to folklore.
