ハロン湾 ヘリテージマラソン 2026【アーリー】（Halong Bay Heritage Marathon 2026)

The Halong Bay Heritage Marathon takes place in November in Vietnam, with runners crossing the UNESCO World Heritage landscape of Ha Long Bay. The event includes a full marathon, half marathon, 10K, and a 2K fun run, catering to serious marathoners, shorter-distance runners, and families. The course is largely flat, and the mild November temperatures are conducive to achieving personal bests. The route hugs the coastline, offering unobstructed views of Ha Long Bay’s limestone karsts and the sea. A notable segment includes crossing Bai Chay Bridge, which the organizers identify as Southeast Asia’s longest single-span bridge. Recent events have attracted over 10,000 participants, and the race is one of the world’s 50 most scenic marathon courses.
