"The Suwon Dulle Gil (Suwon Perimeter Trail) is a 65 kilometer trail that roughly follows the borders of the city of Suwon. The route is about 35 kilometers through the hills in the north and west of the city, about 5 kilometers though some pleasant parks in the east, and about 25 kilometers of city running. It’s a nice tour. You don’t need to start with much water, as there are a ton of convenience stores whenever you enter a city part, or reach the bottom of a mountain. The highest peak is 582 meters. There are some maps along the trail which state that the entire route is 60 kilometers. They are incorrect." (from https://www.toeflresources.com/running-the-suwon-dulle-gil/, which includes further details about the route)
The highlights include Wangsong Lake, Mt. Gwanggyosan, Gwanggyo Lake Park, Suwon Air Base, and Mt. Chilbosan.

I'm attempting this in the coming weeks and am familiar with the Gwanggyo-san area, but not the northwestern sections of the course, am a bit concerned about getting lost, but hope all goes well. Can't wait, and thanks for the .gpx file!
