The Halong Bay Heritage Marathon 2026

If you want a race that feels like a trip, The Halong Bay Heritage Marathon is exactly your kind of adventure in Ha Long, in the province of Quảng Ninh ✅.

Here, you run along the water’s edge with the bay as your backdrop, between sea air and views that make you want to slow down just to take it all in… but you keep your pace 😄.

Whether you’re coming to treat yourself or take on a real challenge, you’ve got options: 5 km, 10 km, 21.0975 km or 42.195 km — same scenery, different sensations, and the same little burst of pride at the finish 💪.

My local guide tip: arrive a bit early to scout the best photo spots and soak up the atmosphere, because in Ha Long, even the warm-up looks like a postcard 📸.

After the finish line, stick around and turn it into the perfect weekend: go for a stroll around Bãi Cháy for that seaside vibe, head up to the Sun World Halong Complex (the view is well worth it), take a break at Hạ Long Park to unwind, and if you want to end on a high note, catch the sunset near Ha Long Bay… you’ll understand why people talk about “heritage”!
