One of my biggest fears about moving to Korea was that my passion for running would take a hit. Pollution, crowded sidewalks, no trails and safety all seemed like possible hindrances. I couldn’t have been more wrong. We found hiking trails minutes from our house. Sidewalks free of people line the streets. Pollution isn’t too bad outside of the yellow dust season in the spring. And if you look both ways when you cross the road then you should be safe.
