The Vibram Hong Kong 100km (HK100) ultramarathon starts today in Sai Kung. The race is a curtain raiser for the Ultra-Trail World Tour, so the field is packed with talent.
Trail running world champion Ragna Debats is lining up on the start line. And so is Jared Hazen, the American speedster with the second fastest time ever at the Western States 100 mile (161km) race in California.
There are a host of lesser known, but equally talented, runners from mainland China, including Liang Jing, who set the course record in 2018 only to be disqualified for taking support outside the checkpoint and Xiang Fuzhao, who was the second woman last year.
