🎁 Souvenirs & Goodies

Every participant (except Mania entries) receives a high-quality souvenir package. While the specific 18th-edition designs are often revealed closer to the date, typical packages include:

1. Official Functional T-shirt: Lightweight, moisture-wicking material.

2. Finisher’s Medal: A commemorative medal featuring the Han River skyline.

3. Finish Line Refreshments: Usually including bread, drinks, and electrolyte supplements.

4. Number Bib & Timing Chip: For accurate record tracking (Half and 10km only).

📈 Course Deep Dive & Analysis

The Ttukseom course is characterized by its zero elevation gain. Unlike city marathons that involve hills or bridges, the riverside path is almost entirely flat.

• The Wind Factor: Because the course runs alongside the Han River, runners may encounter headwinds depending on the weather. It is recommended to run in a group (drafting) to conserve energy if the wind is strong.

• Pacing Strategy: Since there are no hills to break your rhythm, the challenge is maintaining a consistent pace. Avoid starting too fast due to the excitement at the Waterside Plaza; keep your heart rate steady for the first 5km.

• Average Records: Based on previous years, the average 10km finish time is approximately 55–65 minutes, while the Half Marathon average sits around 2 hours and 5 minutes.

👟 Expert Advice: Preparation Checklist

Success on race day depends on your preparation in the weeks leading up to the event.

1. Footwear Selection

Do not wear brand-new shoes on race day! Ensure your running shoes have at least 50km of “break-in” distance. Look for shoes with adequate cushioning to protect your joints from the hard asphalt of the Han River paths.

2. Hydration & Nutrition

• Pre-Race: Carbo-load with rice or pasta 2-3 days before.

• During Race: Drink small sips of water at every station, even if you aren’t thirsty. For the Half Course, consider carrying 1-2 energy gels to consume at the 10km and 15km marks.

3. Injury Prevention

Perform dynamic stretching (leg swings, lunges) before the race. After crossing the finish line, switch to static stretching to help your muscles recover and prevent stiffness.

🤝 Relay & Group Strategy

If you are participating as part of a club or a group of 20+ people, you are eligible for a dedicated team booth and banner.

• Role Allocation: If running as a group, place your most experienced runners at the front to set the pace.

• The “Buddy System”: For 5km and 10km beginners, running with a partner significantly increases the chance of finishing without walking. Encourage each other during the “wall” (usually at the 7km mark for 10km runners).

🚉 How to Get There (Directions)

The Ttukseom Hangang Park is highly accessible via public transport.

• Subway: Ttukseom Park Station (Line 7), Exit 2 or 3. The Waterside Plaza is a short 5-minute walk from the exit.

• Parking: While parking is available at the Han River Park lots, it is highly discouraged on race day. Thousands of participants make parking nearly impossible, and traffic congestion is guaranteed.

• Tip: Arrive at least 1 hour early (by 08:00 AM) to store your belongings and use the restrooms, as queues will be long.

🍽️ Nearby Restaurants

After burning hundreds of calories, a nutritious meal is essential!

1. Jayang-dong Meat Alley: Located near the station, this area offers excellent Korean BBQ (Pork Belly) to replenish protein.

2. Ttukseom Guksu (Noodles): A popular post-run tradition in Korea is eating warm noodles (Kalguksu) or cold noodles (Kong-guksu).

3. Riverside Cafes: For a lighter option, many cafes near Ttukseom Resort offer brunch sets with a view of the river you just conquered.
