Course Characteristics and Heritage

The competition is known for utilizing the diverse terrain of Seoul's mountain parks, featuring a mix of steep granite ascents, forested ridgelines, and technical descents. Unlike traditional road races, the Seoul Trail Run emphasizes self-sufficiency and respect for the natural environment. The course is designed to be accessible to those transitioning from road running while still providing enough vertical gain to satisfy seasoned trail athletes. The rally serves as a cultural bridge, connecting the modern infrastructure of the city with the ancient fortress walls and peaks that have protected Seoul for centuries.

Academy and Training Programs

To support the growing community of mountain runners, the Seoul Ultra Rally also hosts an Academy program. This initiative provides newcomers with essential skills, such as navigating technical terrain, proper gear selection for variable weather, and ultra-endurance pacing strategies. By participating in the rally, runners become part of a broader network that includes other major international challenges like the Mongolia 100 Miles. The organization's customer service center in Jung-gu remains active throughout the week to assist with registration queries and volunteer applications for those who wish to support the race from the sidelines.

About Seoul

Learn more about the host city, Seoul.

Seoul (서울) is the capital of South Korea. With a population of over 9 million, Seoul is by far South Korea's largest city and one of East Asia's financial and cultural centers. A fascinating blend of ancient traditions and cutting-edge digital technology, home to endless street food vendors and vast nightlife districts, an extraordinarily high-pressure educational system and serene Buddhist temples, a dynamic trend-setting youth culture and often crushing conformism, extraordinary architecture and endless monotonous rows of grey apartment buildings, Seoul is a city filled with stark contrasts, contradictions, and paradoxes. People in Seoul can enjoy various artistic activities such as plays, musicals, and concerts.
