Newry, Maine (AP)- A Delaware couple is the winner of the North American Wife Carrying Championship held at the Sunday River Resort in Newry, Maine.

Olivia Rowling and Jerome Roehm of Team Lovebirds from Newark, Delaware, crossed the 278-yard muddy obstacle course Saturday in 55.95 seconds to win the 20th annual event.

Eighty-one teams from Maine to California were scheduled to participate.

Based on Finnish tradition, the event features male competitors completing the obstacle course while carrying a woman. The event is based on Finland’s “Ronkainen the Robber,” whose gang was known to pillage villages and take the women.

Team Lovebirds took home six cases of beer in addition to five times Rowling’s weight in cash, totaling $555.

Rowling and Roehm are eligible to participate in the world championship next year in Finland.
