Best sun protection for Garganta de los Infiernos Mountain Race

April in the Jerte Valley can be sunny. Sun protection recommended on exposed sections.

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.
