Olympic Park Songpa-gu is Seoul's best morning run tourists never discover. Main loop exactly 5km maintained paths through 1988 Olympics venue - the premium circuit among various available running options. Pass iconic Peace Gate, run alongside rowing lake, sculptures throughout.

Practically empty sunrise except serious local runners. Air quality surprisingly good compared central Seoul, free water stations every kilometer. Mongchontoseong station line 8 exit 1, start around 6am full experience. Best choice if you want structured distance and olympic history.

Architecturally fascinating - can see how '88 Olympics shaped this whole district. Venues repurposed but spatial relationships still clear. Shorter 2km inner loop available, but the main 5km circuit is the signature olympic park experience.
