About the Event

The Izu Oshima Marathon takes you through a spectacular, grueling stretch of natural scenery — a stunning seaside route, a deep-green camellia tunnel, and the edge of Mt. Mihara's 'back desert.' Why not run an island race amid rich nature, cheered on by locals, whether you're a beginner or a veteran runner? Sea breeze! Mountain wind! 365m of elevation change! This is Izu Oshima's challenge to you on a genuinely tough course! Entry fees: Full Marathon ¥9,400, Half Marathon ¥7,400, 10km ¥5,400, [Oshima residents] 10km ¥4,400
