Oxfam Trailwalker runners 2XU UFO became the first all-Hong Kong Chinese team last night to win the annual charity event since organisers made the route longer and more arduous in 2009. The achievement was a record in more ways than one, according to team leader Tsang Chun-kit - he said their time of 11 hours 58 minutes in completing the scheduled 48-hour race also beat the last record set by an all-Hong Kong Chinese team, of 12 hours 25 minutes in 2012. "We are very excited because we have broken the records," Tsang, 31, said after they crossed the finish line at 8.28pm. "The weather has been quite wet these days, so maybe people from overseas are not as used to the weather as we are." The youngest in his team, Tsang said one of its members had taken part 20 times before.

This time, its fundraising target was HK$32 million. Participants in teams of four traversed more than 20 hills on the MacLehose and other trails between Sai Kung and Yuen Long, along a 100km route that was 2km longer than before 2009. Previous winners included Nepalese teams, some of whom were former Gurkhas, and the People's Liberation Army's Hong Kong garrison.

They were required to finish within 48 hours, though athletes and professional runners from around the world had been able to complete the gruelling event in far less time, including a record 10 hours and 58 minutes set in 2013 by a team of Nepalis. For the first time, non-participants could track all the teams, including the top 10 finishers, via a live web tracking system . "The No 1 goal is for my team [The Gurkhas] to enjoy it ... and for us to finish as a team," said Shaun Chandler, 39, a British officer with the Brigade of Gurkhas. Chandler was on the winning team at Oxfam's British edition in July. During a pre-run stretch yesterday, he was complimentary about the route. "The scenery is absolutely stunning. I've never seen a trail in 100km with so many different terrains," he said. "There are beaches, hills, rocks and meadows. You have it all."

This year's event roped in more than 3,000 volunteers, 50,000 donors and 5,000 support team members. The Trailwalker race began as a training exercise for Gurkha soldiers – Nepalese fighters who served in the British army. Since 1986, the event that started in Hong Kong, where Gurkha soldiers served for 30 years, spread to 16 cities in 10 countries around the world.
