It is known for its rugged mountain topography that segments the city's various districts, creating a unique urban-nature interface. The demographic profile of Busan is roughly 98% Korean, with a growing international community primarily involved in the shipping, education, and tech sectors. The median household income in Busan is approximately 56 million KRW. The race specifically highlights the Geumjeongsanseong Fortress, the largest mountain fortress in South Korea, which provides a dramatic stone-walled backdrop for the runners as they navigate the technical mountain paths.
