Mexican adventurer David Liaño Gonzalez, who just became the first climber to double summit on Mount Everest in the same climbing season, is planning to set off in September to sail around the world solo.

"It's a great adventure. I have done the maximum in climbing and now I want to do the maximum in sailing, going around the world alone," Liaño told Efe after returning to Nepal from Tibet.

The 33-year-old Liaño Gonzalez reached the summit of Everest on May 19 via the Tibetan north side after climbing to the mountain's top on May 11 from the south side in Nepal.

Mount Everest is 8,848 meters (just over 29,000 feet) tall and located in the Himalayas between China and Nepal.

On May 29, the climbing world will celebrate the 60th anniversary of the first climb to the summit of Mount Everest by Sir Edmund Hillary and Sherpa Tenzing Norgay.

"You cannot go any further than sailing around the world alone," the adventurer said.

The Mexican climber first reached the top of Mount Everest in 2005, when he completed the "seven summits," climbing the world's seven highest peaks.

The climber, a businessman and adventurer who was born in Mexico City, said he did not need sponsors for his sports ventures.

The unmarried Liaño, who has dual Spanish and Mexican citizenship, said he began climbing at 13 and has always had the support of his parents for all his adventures.

"If I were married, I would not take on these challenges. It would be selfish to invest the time and money, and to put myself in danger since I am not a professional climber," Liaño said. EFE
