“It poured that day, and running in soaked shoes made my feet feel incredibly heavy. I learned a lot.”

In the rain at Sunsa half marathon, the runner set a personal best of 1 hour 45 minutes 3 seconds. From 4 km, the runner followed the pacer and rejoined after tying their shoelaces. The runner fell behind on the final hill but finished all the way to the end.
“I registered for half marathon, but due to my condition, I ran the 10K and finished within an hour.”
The runner took part with a running crew and signed up for the half marathon, but ran the 10K instead because of how they were feeling. They finished within an hour and enjoyed the group's booth, the cheering, and sundubu after the race.
“There were even cute cavemen, and because the race was not very large, I enjoyed its modest, warm, friendly atmosphere.”
The runner took part in the 10K and enjoyed the warm, friendly atmosphere of a small local race. A glucose drink before the start upset the runner's stomach, and bicycle traffic along the Han River and the heat from the late start were inconvenient.
“It felt special to run on roads that were closed to traffic like this for the first time.”
The runner finished the Prehistoric Marathon 10K, which starts at the Amsa-dong archaeological site. The runner enjoyed the experience of running on the road and the sports massage after finishing, but was disappointed that bicycles were passing through the course and that traffic control was inadequate.
