Arganza Trail — Cañón del Río Lobos 2026
Recommended sun protection
April in Soria can bring intense sun on exposed sections outside the canyon. Alternates shaded canyon sections with exposed ridges.
Topical sun protection products specific to trail running: SPF 50+ sport sunscreen resistant to water and sweat, SPF lip balm and after-sun for recovery. At altitude, UV radiation increases by 10-12% per 1,000 metres, making sun protection not an extra but mandatory gear.
Based on historical data from the last 10 years
☀️10 hours of sunshine expected. Reapply SPF 50+ every 2 hours.
