About 15,000 people took to the streets of Seoul to participate in a 7.6-kilometer walk traversing the city, on Sunday, the last day of September, which saw clear skies.

The walk began at 8 a.m., from Gwanghwamun Square to Banpo Hangang Park. Sections of roads were closed off from as early as 7 a.m. to as late as 11:30 a.m. to make way for the event’s participants.

The event invited 10,000 walkers, 4,800 cyclists and 200 users of personal mobility devices to sign up online on a first come, first served basis. Those riding bicycles had to be at least 13 years old. Those on PMDs had to have a driver’s license.

The route for cyclists was longer than the one for those walking. Cyclists had to go farther and circle back to the finish line to match the end time with the rest, pedaling for a total of 15 kilometers.
