Ada Tsang Yin-hung is a record-breaking Hong Kong mountaineer, former secondary school teacher, and motivational speaker.
Starting serious mountaineering in 2010 with no previous experience, she underwent years of high-intensity training in ice and rock climbing alongside long-distance running. After her initial attempts on Mount Everest in 2014 and 2015 were thwarted by severe avalanches, she quit her job as a life education teacher in 2017 to train full-time. Later that year, she became the first Hong Kong woman to summit Mount Everest.
In May 2021, during the COVID-19 pandemic, Tsang set a landmark Guinness World Record for the fastest female ascent of Mount Everest, climbing non-stop from Base Camp to the 29,031-foot peak in 25 hours and 50 minutes. (This record was later surpassed by Nepal's Phunjo Lama in 2024).
Continuing her high-altitude speed pursuits, Tsang achieved another milestone in September 2025 by completing the fastest recorded female ascent of Mt. Manaslu (8,163m), climbing from Base Camp to the summit in 18 hours and 53 minutes.
Today, she actively works as a keynote speaker and coach, delivering presentations centred on resilience, goal deconstruction, and overcoming adversity.
