Around six-hundred-50 people from 30 countries managed to run around in the open in North Korea on Sunday without being detained.
They were all participating in the Pyongyang Marathon, which has the added benefit are allowing entrants the rare opportunity to see the North Korean capital by foot.
Foreign registration was up by more than 200 this year from the year before.
Tour agencies say the number would have been much higher, if not for a rigorous screening process and numerous restrictions on foreigners seeking to enter the communist state.
The marathon starts and finishes at Kim Il-sung Stadium and loops around the city center.
It can be run as either a full marathon or a ten kilometer half marathon.
It was only the second North Korean marathon to allow foreigner participation.
