The 16th DMZ International Peace Marathon was held Sunday in Cheorwon, Gangwon Province, with more than 6,000 participants, including 444 foreigners, taking part.
The DMZ Marathon course runs along the border area between North and South Korea.
With the two Koreas still technically at war, participants got a glimpse into the ongoing military tension on the peninsula; the civilian access control area was opened for 15 kilometers for the event.
