Seoul's premier running route follows the Han River through Yeouido Hangang Park - a perfectly flat 10km loop with zero traffic lights, no street crossings, and incredible water views the entire way. This is where Seoul's serious runners train, from dawn joggers to evening fitness groups, making it the city's unofficial running headquarters.

Best Times: Hit the path between 6-7am for sunrise over the river and cooler temperatures, or evening after 6pm when the city lights reflect on the water. Summer mornings are crucial - by 9am the heat becomes brutal.

Logistics: Take Subway Line 5 to Yeouinaru Station, Exit 1 leads directly to the path. Water fountains every 2km keep you hydrated, and clean bathrooms are located at the main park pavilion (4km mark). The path surface is smooth asphalt, perfect for tempo runs without ankle-rolling concerns.

Extensions: Connect to other Hangang parks for longer distances - the path stretches 40km total along Seoul's river system. Banpo Rainbow Bridge (famous for its musical fountain) is 8km east if you want a destination run.

The steady river breeze creates a natural air conditioning effect that makes this feel 5 degrees cooler than city streets. Plus, you're running through the heart of Seoul with skyscraper views most tourists never see from ground level.
