She ain't heavy, she's my wife. That's probably the motto for husbands participating in the 2016 World Wife Carrying Championships in Finland. And this year, a Russian couple overtakes everyone else to win a very unique prize.

Russian couple win Wife Carrying Championships

This bizarre race challenges couples to sprint along a 250-meter track with wives clinging onto their husbands' backs.

Couples traveled from as far as Japan, America and Russia to run their way to victory in the annual contest.

"This is such a difficult track. It's so long and you must be fast, strong and have good stamina," said Taisto Miettinen, five-time wife carring world champion.

"We worked hard and now we have a good result. We are happy, it's fantastic," said Dmitriy Sagal, Anastasia Loginova, Russian champions.
