By participating, your sweat and effort transform into a beacon of hope, providing medical funds and emotional support to young warriors and their families.
In a world that moves so fast, the SimSimRun invites you to slow down and “connect heart to heart.” Whether you are a seasoned marathoner or a beginner looking for a meaningful first race, this event offers a unique platform where every step counts toward a child’s recovery. Join thousands of participants at the Han River as we run for a future where every child can smile and play without pain.

๐ฃ๏ธ Course Details & Analysis
๐๏ธ Course Layout
The race takes place along the scenic Han River in Seoul, starting from the Yeouido Mulbit Square.
10km Course: Designed for those who want a moderate challenge. It stretches along the riverbank, offering a refreshing breeze and panoramic views of the city skyline.
5km Course: A popular choice for casual runners and joggers. Itโs relatively flat and perfect for maintaining a steady pace.
3km Course: Ideally suited for families, children, and elderly participants. This course emphasizes the “charity walk” aspect more than competitive speed.
๐ Difficulty Analysis
Terrain: The Han River courses are famous for being exceptionally flat. There are no significant inclines, making it an ideal venue for setting a Personal Best (PB).
Difficulty Rating: Low (1/5). The primary challenge is the June weather, which can be humid.
Time Limit: There is a generous time limit of 1 hour and 30 minutes for all courses, ensuring that even those walking the 10km can finish comfortably.

Nongshim Baeksansoo: Unlimited mineral water to keep you hydrated.

๐ก Expert Advice: Preparation & Strategy
๐ Running Gear Checklist
For a June race, heat management is key.
Shoes: Do not wear brand-new shoes on race day. Ensure you have “broken in” your running shoes at least 2-3 weeks prior.
Socks: Use synthetic moisture-wicking socks to prevent blisters. Avoid 100% cotton.
Sun Protection: Even at 9 AM, the sun can be harsh. Apply SPF 50+ sunscreen and consider a light running cap.
๐ฉน Injury Prevention
Dynamic Stretching: Before the race, focus on leg swings and hip rotations to wake up your muscles.
Hydration Strategy: Drink 300-500ml of Baeksansoo water 1 hour before the start. During the race, take small sips at every water station even if you don’t feel thirsty.
๐โโ๏ธ Relay & Group Strategy
While this is an individual race, many run in groups.
Pacing: If running with friends, appoint a “Pacer” who maintains a steady speed.
Safety First: The Han River path is narrow in some sections. When running in a group, avoid running more than two-abreast to allow other runners to pass.
๐ How to Get There (Directions)
Yeouido Hangang Park is centrally located and highly accessible.
Subway (Recommended): Take Line 5 to Yeouinaru Station. Use Exit 2 or Exit 3. The Mulbit Square is a 5-minute walk from there.
Bus: Numerous buses stop at “Yeouido Park” or “Yeouinaru Station.”
Car: Parking is available at the Yeouido Hangang Park parking lots, but it is extremely limited on event days. It is highly advised to use public transport to avoid delays.
๐ฝ๏ธ Nearby Restaurants (Post-Race Recovery)
After burning calories for a good cause, treat yourself in the Yeouido area!
Yeouido Hangang Ramen: Experience the classic “Ramen Machine” at the convenience stores near the park. It’s a rite of passage for Han River runners.
The Hyundai Seoul (Mall): A 10-minute walk away, offering a massive food hall with cuisines ranging from premium Korean beef to trendy desserts.
Jinju Jip: Famous for its Kong-guksu (Cold Soy Milk Noodles). It is the ultimate protein-rich recovery meal for a warm June day.
