第11回 びわ湖バレイスカイラン

Biwako Valley Skyrun is an outdoor mountain-running event based at Biwako Valley in Otsu City, Shiga Prefecture. Its stated concept is to raise interest in the Hira Mountains, a symbolic range for Otsu, and in mountain climbing as a healthy form of exercise. The event also aims to promote Otsu City's natural environment, local culture, and the scenery of Biwako Valley through an outdoor sporting experience. It is organized by the Biwako Valley Skyrun Executive Committee, planned by Skyrunning Japan LLC, and supported by Biwako Valley, with backing from local government, tourism, sports, and mountaineering organizations. The source text emphasizes that the routes pass through a natural mountain environment shared with the general public, so participants are expected to respect safety, other users, and environmental protection. Runners must stay on the designated course, avoid littering, and refrain from collecting or damaging plants, animals, fungi, rocks, or other natural features. As a mountain event, participation requires awareness of inherent outdoor risks, with competitors taking responsibility for injury, illness, or accidents while the organizer provides first aid. The event setting combines steep mountain terrain, views associated with Biwako Valley, and the broader natural and cultural appeal of Otsu City.
