The Gamania Shore to Summit Ultramarathon is rooted in the “Mountains to Sea National Greenway,” one of Taiwan’s seven major greenways. It is a pilgrimage of adventure, tracing 400 years of history and the cultural soul of Taiwan.

As Taiwan’s most grueling road ultra—and Asia’s leader in total elevation change—this race redefines the limits of endurance. Runners must conquer 177 kilometers and a staggering 6,047 meters of total ascent and descent within 24 hours. From tropical lowlands to alpine tundras, participants will face a temperature swing of over 20°C in a single day, a true test of physical stamina and mental fortitude.

With its unique geographic span and elite-level difficulty, the Gamania Shore to Summit has become a premier stage for world-class runners. It draws top athletes from across the globe to Taiwan to witness a new pinnacle in Asian road ultramarathons.
