第7回 小豆島一周ウルトラウォーキング2026

Shodoshima’s coastline is the hook here: the island is the second largest in the Seto Inland Sea, with a rias coast and a south shore that draws clean, beautiful curves. The 7th Shodoshima Ultra Walking 2026 has the feel of a long, plain-spoken island effort, the kind where the view helps but the distance still has to be earned.
