🏃 What exactly is Insider Run W?

Have you ever imagined running through a massive exhibition hall? Insider Run W is not your typical marathon. It is the world's first regular 10K indoor circuit race, taking place at the iconic Ilsan KINTEX in South Korea.

The event transforms KINTEX Exhibition Halls 2 and 3 into a professional-grade running track. Participants complete a 1km loop exactly 10 times to reach the 10km mark. It is a fusion of a sports competition and a vibrant festival atmosphere.

💡 The 2026 event features DJ performances and high-tech lighting, making every lap feel like a party rather than a chore.

❄️ Why Indoor Running is the Perfect Choice

In January, Korea's weather can be quite harsh with biting cold and unpredictable fine dust. Indoor running offers a safe and comfortable haven for athletes who don't want to skip their training.

The climate-controlled environment of KINTEX ensures an optimal temperature and humidity level. This allows runners to maintain a consistent pace without the resistance of wind or slippery, icy roads. It is the perfect setting for a personal best!

🔥 Dynamic Energy and Korean Running Culture

The "O-Woon-Wan" (Today's Workout Complete) trend is huge in Korea. At Insider Run W, you can feel the incredible passion of Korean running crews as they celebrate the end of the month with high-octane energy.

The event is not just about the race; it's about community. You'll see thousands of people cheering, taking photos at trendy zones, and enjoying the finisher's medals. It's a true festival that unites office workers, students, and pro athletes.

💡 How to Enjoy the Festival to the Fullest

To make the most of your 2026 Insider Run W experience, preparation is key. Since you'll be running on a flat, hard exhibition floor, wearing high-quality running shoes with good cushioning is highly recommended.
