Thirty-four-year-old Hau Ha Thi only started running in August of 2020, but has yet to be beaten in a race. She’s won the 70K Vietnam Trail Marathon, the 100K Vietnam Mountain Marathon, the 54K Doi Inthanon by UTMB, the 75K Mt. Apo Sky and Vertical Race, the UTA Australia by UTMB 50K, and most recently the 35K XTERRA Asia-Pacific Championships that took place in Southern Taiwan’s Kenting National Park in April of 2023.
There, on the same trails that had all but destroyed numerous international pro triathletes the day before, Ha Thi finished almost 30 minutes ahead of the second-place female and behind just two of the men. She may very well have contended for the overall win, as she’s done in every other race she’s entered throughout her young running career, but stomach issues and cramping forced her to stop multiple times during the race.
Turns out, Ha Thi only started running because, she says with a giggle through a Zoom call, “I don’t work. I get fat.” A ridiculous notion considering the diminutive runner had only gained a few kilos. She had lost her job in the tourism department of Sapa, Vietnam—a hotspot for tourism—during the pandemic when travel all but ceased around the world. Roughly a month after she started running, she entered and beat all of the competitors, male and female, in a 21K in Sapa. She had only run on a trail once before; her regular runs (for the month she’d been running) consisted of a flat 4K around the lake in Sapa, which she did twice a day to get fit. “When I woke up after the race,” she says, “I could not move my back.” Surprise: she was a little sore.
"I don't worry about the people around me. I run with my speed and I feel good.”
She's since lost the weight she was upset about gaining, but she’s won everything else.
