Looking at photos on her phone, Eva Lobo could see that her husband's legs had multiple scratches, and that he had encountered venomous snakes numerous times.

However, the images were a normal sight for Lobo whenever her husband is gone on rescue missions to help locate individuals missing in mountains. This time, he was in the Gaotaishan mountain range in Hsinchu County.

Lobo, 42, is an indigenous Taiwanese from Nantou County whose parents hail from the Atayal and Seediq peoples respectively. Her tracker husband, on the other hand, is from the Czech Republic.

Fans and fellow trail runners would have a better chance of finding Petr Novotny speeding through the mountains and hills around Taiwan rather than in populated areas.

Nicknamed "Beast Runner," the 36-year-old Czech national is arguably a legend amongst outdoor lovers and athletes in Taiwan, having set multiple amateur trail-running records across the island. He is also a regular on mountain search missions all over the country.

Before he came to Taiwan, Novotny was just a casual athlete and outdoor lover. As a teenager, he enjoyed scouting (camping and hiking) a lot as he is an explorer at heart.

"I like to go places," Novotny said during an interview with CNA on Sept. 29. "While the Czech Republic is not as wild (as Taiwan), I did a lot of exploring and camping."
