Wan Jin Shi Marathon: The Complete Guide to North Coast Coastal Scenery and Wind Speed Challenges

Introduction

The Wanjinshi Marathon is one of Taiwan’s most distinctive coastal marathons. The course starts in Wanli District, New Taipei City, passes through Jinshan and Shimen, and runs along Provincial Highway 2 on the North Coast, accompanied by the magnificent Pacific Ocean views throughout. However, this beautiful course also hides a formidable opponent—the northeast monsoon. Held every March, winds from the sea can reach 8–12 on the Beaufort scale, making it the most critical natural factor affecting performance.

Full Course Overview

The Wanjinshi Marathon starts and finishes at Wanli Junior High School, extending entirely along Provincial Highway 2’s coastal road—one of the few marathons in Taiwan where you can see the ocean for the entire race.

The course is an out-and-back format. The first half heading north is mostly into a headwind, while the return in the second half benefits from a tailwind—a key basis for developing your pacing strategy.

Wind Speed Management: The Core Challenge

The northeast monsoon is the biggest variable at the Wanjinshi Marathon. Here are strategies for dealing with wind speed:

Headwind Section (0–25K):

• Slow your pace by 15–30 seconds per kilometer; don’t push through it
• Lower your center of gravity, reduce your frontal area, and lean slightly forward
• Draft behind runners ahead of you to form a “windbreak train,” saving 10–15% of your energy
• Keep your heart rate below your target pace heart rate; adjust by wind force rather than time

Tailwind Section (25–42K):

• Seize the tailwind opportunity to speed up, running 10–20 seconds/km faster than your normal pace
• Stay relaxed and let the wind help propel you forward
• Release the energy saved in the first half here

Coastal Climate Considerations

March temperatures on the North Coast range from 14–20°C, but the sea breeze makes it feel colder:

• Windproof outer layer: A lightweight windbreaker vest is essential gear; wearing a thick jacket the whole way is not recommended
• Sun protection: March sunlight reflects strongly off the North Coast; protect your face and neck
• Salt replenishment: In the sea breeze environment, sweat evaporates quickly, making it easy to underestimate fluid loss; increase electrolyte intake frequency

Aid Station Highlights

Wanjinshi Marathon aid stations feature North Coast flavors:

• Jinshan sweet potatoes are the signature offering, rich in carbohydrates and minerals
• Some stations provide warm ginger soup, highly effective against the chill of the sea wind
• The finish line offers Wanli crab soup (varies by year)
• Official aid consists mainly of water and sports drinks, with stations every 2.5K

Pacing Reference

Considering wind factors, it’s recommended to build in a 10–15 minute buffer when setting your target time:

• Sub-3:30 goal: Control headwind sections at 5:00–5:10/km, aim for 4:40–4:50/km on tailwind sections
• Sub-4:00 goal: 5:40–5:50/km on headwind sections, 5:20–5:30/km on tailwind sections
• Finish-focused: 6:10–6:30/km on headwind sections, 5:50–6:00/km on tailwind sections

Practical Tips

• Check wind forecasts before race day: The weather bureau updates North Coast wind speeds daily; start tracking three days before the race
• Lip balm and moisturizer: The sea wind is drying; lips and skin are especially prone to chapping
• Earplugs as backup: The howling wind can sometimes affect concentration; some runners prefer using earplugs

Conclusion

The Wanjinshi Marathon is a race against nature. The grandeur of the ocean views makes you forget the wind’s resistance, yet every step reminds you it’s there. When you spread your wings on the tailwind section and gaze over the Pacific, all the effort becomes worthwhile. This isn’t just a marathon—it’s a conversation with the ocean.
