The couple that climbs together, stays together.

Every couple has their fun, romantic hobby that they love to do together. For this couple, it's scaling the world’s tallest peaks.

Romano Benet and Nives Meroi, both 55 and from Italy, have become the first couple to conquer the world’s 14 highest summits after completing a climb to the top of Annapurna peak, in the Himalayan Mountains, in Nepal.

The 26,545-foot summit was “the hardest but also the most beautiful,” said Meroi, according to Italian publication The Local.

Annapurna is considered one of the most difficult summits to climb apart from Mount Everest. The couple reportedly completed the climb without oxygen tanks.

Only 34 other climbers in the world have documented their climbs to all 14 of the world’s highest peaks. The first mountaineer to make such an achievement was Reinhold Messner, in 1986.

The 14 peaks are all above 8,000 feet, which is why they're referred to as “eight-thousanders.” They include: Everest, K2, Kangchenjunga, Lhotse, Makalu, Cho Oyu, Dhaulagiri, Manaslu, Nanga Parbat, Annapurna, Gasherbrum, Broad Peak, Gasherbrum, and Shishapangma.

Meroi, according to The Local, was on track to become the first female to complete the record in 2009, but the couple had to take a break due to Benet’s health. They resumed climbing in 2012.

After conquering such great heights, who knows how this adventurous couple will find new thrills at sea level.
