About this Race

The Seoul Marathon is one of Asia's elite races and among the fastest courses on the continent, a largely flat route through the South Korean capital that starts near Gwanghwamun Square and finishes inside the Jamsil Olympic Stadium. The course runs on wide, smooth roads past palaces and the Han River, with a gentle profile that consistently yields quick times and strong international fields. Held in March, it offers cool, favorable spring conditions and the polished organization typical of a top-tier Asian marathon. The few rises are minor, leaving fitness and pacing as the main determinants. It suits the PB-focused runner who wants a fast course and an Olympic-stadium finish without the lottery odds of the bigger majors.

Course Insight

Seoul is a flat, fast spring course that runs along the Han River through a modern city built for quick times, finishing inside the 1988 Olympic Stadium. With the terrain offering no natural brakes, holding back early is entirely self-imposed. Cold March air keeps legs fresh and fast if you're dressed to start cool and warm into it. The riverside straights can carry a breeze worth sheltering from in a pack. Pace it evenly and the stadium finish becomes a celebration rather than a struggle.

Pro tip: Dress to start cool and warm into it in the March chill, then ride even pacing to the Olympic Stadium finish.
