Caramulo 100

Caramulo 100 is a mountain trail running series in Tondela, Viseu District, Portugal, held around mid-September. It features two long off-road distances in the Serra do Caramulo: a 100 km race and a 169 km race, both qualifying for the UTMB Index. The terrain is central: mountain paths, forest, and nature, not city streets. The 169 km route ascends approximately 6,250 metres, while the 100 km route includes about 3,840 metres of ascent and is the more popular choice. This event challenges runners seeking a serious Portuguese trail run, where pacing, night running, and mountain experience are crucial.
