Best sun protection for Desafío Trail Templario

March in the sierra can surprise with intense sun on exposed sections, especially at altitude.

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.
